POWER OPERATIONAL AMPLIFIERS PA10 e PA1OA (800) 546-APEX MICROTECHNOLOGY FEATURES GAIN BANDWIDTH PRODUCT 4MHz TEMPERATURE RANGE 55 to +125C (PA10A) EXCELLENT LINEARITY Class A/B Output WIDE SUPPLY RANGE +10V to +50V HIGH OUTPUT CURRENT +5A Peak APPLICATIONS * MOTOR, VALVE AND ACTUATOR CONTROL MAGNETIC DEFLECTION CIRCUITS UP TO 4A POWER TRANSDUCERS UP TO 100kHz TEMPERATURE CONTROL UP TO 180W PROGRAMMABLE POWER SUPPLIES UP TO 90V AUDIO AMPLIFIERS UP TO GOW RMS DESCRIPTION The PA10 and PA10A are high voltage, high output current operational amplifiers designed to drive resistive, inductive and capacitive loads. For optimum linearity, the output stage is biased for class A/B operation. The safe operating area (SOA) canbe observed for all operating conditions by selection of user programmable current limiting resistors. Both amplifiers are internally compensated for all gain settings. For continuous operation under load, a heatsink of proper rating is recom- mended. This hybrid integrated circuit utilizes thick film (cermet) resistors, ceramic capacitors and semiconductor chips to maxi- mize reliability, minimize size and give top performance. Ultra- sonically bonded aluminum wires provide reliable interconnec- tions at all operating temperatures. The 8-pin TO-3 package is hermetically sealed and electrically isolated. The use of com- pressible isolation washers voids the warranty.

VOLTAGE-TO-CURRENT CONVERSION DC and low distortion AC current waveforms are delivered to a grounded load by using matched resistors (A and B sections) and taking advantage of the high common mode rejection of the PA10. Foldover current limit is used to modify current limits based on output voltage. When load resistance drops to 0, the current is limited based on output voltage. When load resistance drops to 0, the current limit is 0.79A resulting in an internal dissipation of 33.3 W. When output voltage increases to 36V, the current limit is 1.69A. Refer to Application Note 9 on foldover limiting for details.

Addi- tional information can be found in the application notes. For information on the package outline, heatsinks, and mounting hardware, consult the Accessory and Package Mechanical Data section of the data book. SAFE OPERATING AREA (SOA) The output stage of most power amplifiers has three distinct limitations: 1. The current handling capability of the transistor geometry and the wire bonds. 2. The second breakdown effect which occurs whenever the simultaneous collector current and collector-emitter voltage exceeds specified limits. 3. The junction temperature of the output transistors. 5.0 < wn 7 30 Tb tts 3 To 2 20 = 5% +15 * 85. 5 fo e 49 ss 5 Z7 c 5 e. oO 5 3 2 a 2 2 10 18 20 25 30 3540 50 60 7080 100 SUPPLY TO OUTPUT DIFFERENTIAL VOLTAGE Vg -Vo (V) The SOA curves combine the effect of these limits. For a given application, the direction and magnitude of the output current should be calculated or measured and checked against the SOA curves. This is simple for resistive loads but more complex for reactive and EMF generating loads. However, the following guide- tines may save extensive analytical efforts. 1. Capacitive and dynamic inductive loads up to the following maximum are safe with the current limits set as specified.

The amplifier can handle any EMF generating or reactive load and short circuits to the supply rail or shorts to common if the current limits are set as follows at T, = 85C: MB 0878636 00023463 145 @& CONSIDERATIONS SHORT TO +V, SHORT TO +V, C, L, OR EMF LOAD COMMON 50V .26A .B4A 40V .38A 1.1A 35V ASA 1.2A 30V 65A 1.44 25V 848 1.7A 20V 1.1A 2.2A 15V 1.4A 2.9A These simplified limits may be exceeded with further analysis using the operat- ing conditions far a specific application. CURRENT LIMITING Refer to Application Note 9, "Current Limiting", for details of both fixed and foldover current limit operation. Visit the Apex web site at www.apexmicrotech.com for a copy of llimit.xls which plots current limits vs. steady state SOA. Beware that current limit should be thought of as a +/-20% function initially and varies about 2:1 over the range of -55C to 125C. For fixed current limit, leave pin 7 open and use equations 1 and 2. Ro = 0-65/L. (1) Ig, = 0.65/Re. (2) Where: I, is the current limit in amperes. Re, is the current limit resistor in ohms. For certain applications, foldover current limit adds a slope to the current limit which allows more power to be delivered to the load without violating the SOA. For maximum foldover slope, ground pin 7 and use equations 3 and 4. 0.65 + (Vo * 0.014) 3) k= 3 Re. 0.65 + (Vo * 0.014) Ro = (4) Ten Where: Vo is the output voltage in volts. Most designers start with either equation 1 to set Ro, for the desired current at Ov out, or with equation 4 to set R,, at the maximum output voltage. Equation 3 should then be used to plot the resulting foldover limits on the SOA graph. If equation 3 results in a negative current limit, foldover slope must be reduced. This can happen when the output voltage is the opposite polarity of the supply conducting the current. In applications where a reduced foldover slope is desired, this can be achieved by adding a resistor (Ryo) between pin 7 and ground. Use equations 4 and 5 with this new resistor in the circuit. 0.65+ Vo* 0.14 10.14+R I= Eo (5) Rev 0.65+ Vo* 0.14 10.14 + Reo Ro= (6) Te Where: Reg is in K ohms. C132 PALOU REY.
