The FET input and high-performance characteristics, including wide bandwidth and fast settling, make it useful for a variety of applications in the processing of video signals. Recent innovations in circuit design have been incorporated into the HOS-060 to make it extremely useful to the designer who needs outstanding performance in current boosting, voltage amplification, impedance matching, or a multiplicity of other high-frequency requirements. Voltage offset and its temperature coefficient have been dramati- cally improved in the HOS-060; offset is as low as on most monolithic op amps, despite being a thick-film hybrid. These improvements, moreover, have been accomplished with- out any sacrifice in the other parameters which characterize its outstanding performance in video applications. The HOS-060 op amp is pin-for-pin compatible with its forerunner HOS-050 and is useable in the same diversity of video require- ments. The reader is strongly urged to refer to the six-page data sheet for the HOS-050 op amp to obtain additional insight and details on potential uses for the HOS-060. The HOS-060 Operational Amplifier is housed in an industry standard TO-8 metal can and operates over a case temperature range of 55C to + 125C; the model number for the standard unit is HOS-060SH. For units processed to MIL-STD-883, Method 5008, specify model number HOS-060SH/883. Information furnished by Analog Devices is believed to be accurate and reliable.

One of the most common uses of video op amps is for D/A converter output voltage amplification or current boosting. Figure 3 is one example of this type of application. In this circuit, the internal resistance of the D/A is the feed-forward resistor for the op amp. ~18V + 16V o O.1pF 7 O.1yF ch ms ant HDS ?

Inverting Unipolar or Bipolar Voltage Output The circuit which is shown will provide a negative unipolar output with binary coding on the input, and bipolar offset ground- ed. It will provide a bipolar output with complementary offset binary coding on the input, and bipolar offset connected to Io. OFFSET AND GAIN ADJUSTMENT The low value of offset may preclude the need for adjustment, but Figure 4 shows a method of adjusting both offset and gain.

HOS-060 Offset and Gain Adjust As shown, the gain of the circuit is established by the equation: Rp G=- (2) where Reg = Rgain + Gain Adjust. Once the user has established the desired gain for the illustrated circuit, the value of Rpg can be used to determine the correct value of Rorrser with the equation: RorrseT = ~ (Yo 5) where AEg is the desired amount of offset on the output. Note: Rep, Ream; Crg and Roreser must be located as close to the summing node of the HOS-060 as physically possible. This helps prevent additional capacitance in the summing node and corresponding bad effects on frequency response and settling times. Variable controls (such as Offset Adjust and Gain Adjust) should never be tied to the summing node of the op amp. Their correct electrical locations are those shown in Figure 4. NONINVERTING OPERATION The vast majority of video operational amplifiers display marked differences in settling times and bandwidths when operated in a noninverting mode instead of the inverting mode. There are a number of valid reasons for this characteristic. Most high-speed op amps use feed-forward compensation for optimizing performance in the inverting mode. This is necessary to obtain wide gain-bandwidth products while maintaining dc performance in these types of devices. In effect, the op amp has a wideband ac channel which is not perfectly matched to the dc channel. Feed-forward techniques enhance the performance of the op amp in the inverting mode by increasing the slew rate and small- signal bandwidth. These techniques, however, also decrease the amplifiers tolerance to stray capacitances, so must be employed judiciously. The Analog Devices HOS-060 has different performance charac- teristics when operating as a noninverting amplifier, but the care used in the design makes the differences less pronounced than they are in many competing units. The HOS-060 can be considered a true differential video op amp. It requires little or no external compensation because its rolloff characteristics approach a 6dB/octave slope. This helps the user determine summing errors and loop response; and helps assure the stability of the system. The performance parameters for both inverting and noninverting operation are shown elsewhere in this data sheet (see SPECIFI- CATIONS section and figures). A comparison of the characteristics will highlight the similarities in performance, with the exceptions noted above.
