G | Page 8 of 16 01909-027 INPUT OFFSET CURRENT (nA) 4 AD8565/AD8566/AD8567 THEORY OF OPERATION Operation of the input stage is best understood as a function of applied common-mode voltage: when the inputs of the AD8565/ AD8566/AD8567 are biased midway between the supplies, the differential signal path gain is controlled by resistive loads Q4 to Q5 (via R9, R10). As the input common-mode level is reduced toward the negative supply (VNEG or GND), the input transistor current sources, I1 and I2, are forced into saturation, thereby forcing the Q6 to D3 and Q8 to D4 networks into cutoff. However, Q4 to Q5 remain active, providing input stage gain. Inversely, when common-mode input voltage is increased toward the positive supply, Q4 to Q5 are driven into cutoff, Q3 is driven into saturation, and Q4 becomes active, providing bias to the Q10 to Q11 differential pair. The point at which the Q10 to Q11 differential pair becomes active is approximately equal to (VPOS - 1 V). VPOS R1 Q3 BIAS LINE Q4 D1 D2 R3 R4 Q6 R5 D3 R6 C2 Q10 D4 Q11 D5 I1 I2 D6 600 200 0 -200 -400 -600 -800 -1000 0 2 4 6 8 10 12 INPUT COMMON-MODE VOLTAGE (V) 14 16 Figure 29. AD8565/AD8566/AD8567 Input Bias Current vs. Common-Mode Voltage To achieve rail-to-rail output performance, the AD8565/ AD8566/AD8567 design uses a complementary commonsource (or gmRL) output. This con-figuration allows output voltages to approach the power supply rails, particularly if the output transistors are allowed to enter the triode region on extremes of signal swing, which are limited by VGS, the transistor sizes, and output load current. In addition, this type of output stage exhibits voltage gain in an open-loop gain configuration. The amount of gain depends on the total load resistance at the output of the AD8565/AD8566/AD8567. FOLDED CASCADE R10 VNEG 01909-028 R9 400 As with any semiconductor device, whenever the input exceeds either supply voltages, attention needs to be paid to the input overvoltage characteristics. As an overvoltage occurs, the amplifier could be damaged, depending on the voltage level and the magnitude of the fault current. When the input voltage exceeds either supply by more than 0.6 V, internal positive-negative (pn) junctions allow current to flow from the input to the supplies. V- Q5 Q4 VS = 16V TA = 25C 800 INPUT OVERVOLTAGE PROTECTION Q8 C1 V+ 1000 01909-029 Figure 28 shows a simplified equivalent circuit for the AD8565/ AD8566/AD8567. The rail-to-rail bipolar input stage is composed of two PNP differential pairs, Q4 to Q5 and Q10 to Q11, operating in series with diode protection networks, D1 to D2. Diode network D1 to D2 serves as protection against large transients for Q4 to Q5 to accommodate rail-to-rail input swing. D5 to D6 protect Q10 to Q11 against Zenering. In normal operation, Q10 to Q11 are off, and their input stage is buffered from the operational amplifier inputs by Q6 to D3 and Q8 to D4. The benefit of this type of input stage is low bias current. The input bias current is the sum of base currents of Q4 to Q5 and Q6 to Q8 over the range from (VNEG + 1 V) to (VPOS - 1 V). Outside this range, the input bias current is dominated by the sum of base currents of Q10 to Q11 for input signals close to VNEG and of Q6 to Q8 (Q10 to Q11) for signals close to VPOS. From this type of design, the input bias current of the AD8565/ AD8566/AD8567 not only exhibits different amplitude but also exhibits different polarities. Figure 29 provides the characteristics of the input bias current vs. the common-mode voltage. It is important to keep in mind that the source impedances driving the inputs are balanced for optimum dc and ac performance. INPUT BIAS CURRENT (nA) The AD8565/AD8566/AD8567 are designed to drive large capacitive loads in LCD applications. They have high output current drive and rail-to-rail input/output operation and are powered from a single 16 V supply. They are also intended for other applications where low distortion and high output current drive are needed. Figure 28. AD8565/AD8566/AD8567 Equivalent Input Circuit Rev. G | Page 9 of 16 AD8565/AD8566/AD8567 The AD8565/AD8566/AD8567 are immune to phase reversal. Although device output does not change phase, large currents due to input overvoltage could damage the device. In applications where the possibility of an input voltage exceeding the supply voltage exists, overvoltage protection should be used as described in the Input Overvoltage Protection section. POWER DISSIPATION The maximum allowable internal junction temperature of 150C limits the maximum power dissipation of AD8565/ AD8566/AD8567 devices. As the ambient temperature increases, the maximum power dissipated by AD8565/AD8566/ AD8567 devices must decrease linearly to maintain maximum junction temperature. If this maximum junction temperature is exceeded momentarily, the device still operates properly once the junction temperature is reduced below 150C. If the maximum junction temperature is exceeded for an extended period, overheating could lead to permanent damage of the device. The maximum safe junction temperature, TJMAX, is 150C. Using the following formula, the maximum power that an AD8565/ AD8566/AD8567 device can safely dissipate as a function of temperature can be obtained: PDISS = TJMAX - TA/JA where: PDISS is the AD8565/AD8566/AD8567 power dissipation. TJMAX is the AD8565/AD8566/AD8567 maximum allowable junction temperature (150C). TA is the ambient temperature of the circuit. JA is the AD8565/AD8566/AD8567 package thermal resistance, junction-to-ambient. PDISS = (VS - VOUT) x ILOAD where: VS is the supply voltage. VOUT is the output voltage. ILOAD is the output load current. Figure 30 shows the maximum power dissipation vs. temperature. To achieve proper operation, use the previous equation to calculate PDISS for a specific package at any given temperature or use Figure 30. 1.25 16-LEAD LFCSP 1.00 0.75 14-LEAD TSSOP 8-LEAD MSOP 0.50 5-LEAD SC70 0.25 0 -35 -15 5 25 45 AMBIENT TEMPERATURE (C) 65 85 01909-030 OUTPUT PHASE REVERSAL The power dissipated by the device can be calculated as MAXIMUM POWER DISSIPATION (W) This input current is not inherently damaging to the device as long as it is limited to 5 mA or less. If a condition exists using the AD8565/AD8566/AD8567 where the input exceeds the supply more than 0.6 V, an external series resistor should be added. The size of the resistor can be calculated by using the maximum over-voltage divided by 5 mA. This resistance should be placed in series with either input exposed to an overvoltage. Figure 30. Maximum Power Dissipation vs. Temperature for 5-Lead SC70, 8-Lead MSOP, 14-Lead TSSOP, and 16-Lead LFCSP Packages THERMAL PAD--AD8567 The AD8567 LFCSP comes with a thermal pad that is attached to the substrate. This substrate is connected to the most positive supply, that is, Pin 3 in the LFCSP package and Pin 4 in the TSSOP package. To be electrically safe, the thermal pad should be soldered to an area on the board that is electrically isolated or connected to VDD. Attaching the thermal pad to ground adversely affects the performance of the part. Soldering down this thermal pad dramatically improves the heat dissipation of the package. It is necessary to attach vias that connect the soldered thermal pad to another layer on the board. This provides an avenue to dissipate the heat away from the part. Without vias, the heat is isolated directly under the part. Rev. G | Page 10 of 16 AD8565/AD8566/AD8567 TOTAL HARMONIC DISTORTION + NOISE (THD + N) LCD PANEL APPLICATIONS The AD8565/AD8566/AD8567 feature low total harmonic distortion. Figure 31 shows THD + N vs. frequency. The THD + N over the entire supply range is below 0.008%. When the device is powered from a 16 V supply, the THD + N stays below 0.003%. Figure 31 shows the AD8566 in a unity noninverting configuration. The AD8565/AD8566/AD8567 amplifier is designed for LCD panel applications or applications where large capacitive load drive is required. It can instantaneously source/sink greater than 250 mA of current. At unity gain, it can drive 1 F without compensation. This makes the AD8565/AD8566/AD8567 ideal for LCD VCOM driver applications. To evaluate the performance of the AD8565/AD8566/AD8567, a test circuit was developed to simulate the VCOM driver application for an LCD panel. Figure 32 shows the test circuit. Series capacitors and resistors connected to the output of the op amp represent the load of the LCD panel. The 300 and 3 k feedback resistors are used to improve settling time. This test circuit simulates the worst-case scenario for a VCOM. It drives a represented load that is connected to a signal switched symmetrically around VCOM. 10 THD+N (%) 1 VS = 2.5V Figure 33 shows a scope photo of the instantaneous output peak current capability of the AD8565/AD8566/AD8567. 100 1k FREQUENCY (Hz) 10k 30k 300 INPUT 0V TO 8V SQUARE WAVE WITH 15.6s PULSE WIDTH Figure 31.
