Their complementary collector output stage can swing close to the supply rails and is protected against inductive kickback. For optimum linearity, the output stage is biased for class A/B operation. The safe operating area (SOA) can be observed for all operating conditions by selection of user programmable, current limiting resistors (down to 10mA). Both amplifiers are internally compensated but are not recommended for use as unity gain followers. For continuous operation under load, mounting on a heatsink of proper rating is recommended. These hybrid integrated circuits utilize thick film (cermet) resistors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasonically bonded aluminum wires provide reliable inter- connections at all operating temperatures. The 8-pin TO-3 package is hermetically sealed and electrically isolated. Isolation washers are not recommended. The use of com- pressible thermal washers and/or improper mounting torque will void the product warranty. Please see General Operat- ing Considerations.

The circuit above utilizes not only the feature of low internal loss of the PAO2, but also its very low distortion level to implement a crystal clear audio amplifier suitable even for airborne applications. This circuit uses AC coupling of both the input signal and the gain circuit to render DC voltage across the speaker insignificant. The resistor and capacitor across the inputs form a stability enhancement network. The 0.27 ohm current limit resistors provide protec- tion in the event of an output short circuit.

Lang term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF. awh The power supply voltage for all specifications is the TYP rating unless otherwise noted as a test condition. +V, and V, denote the positive and negative supply rail respectively. Total V, is measured from +V, to Vs. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz. Exceeding CMV range can cause the output to latch. . Full temperature specifications are guaranteed but not 100% tested. The internal substrate contains beryilia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or subject to temperatures in excess of 850C to avoid generating toxic fumes.

Additional 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 handbook. SAFE OPERATING AREA (SOA) The SOA curves combine the effect of alt limits for this Power Op Amp. For a given applica- tion, the direction and magni- tude of the output current should be calculated or measured and checked against the SOA curves. This is simple for resis- tive loads but more complex for reactive and EMF generating loads. The following guidelines may save extensive analytical efforts: 1. Under transient conditions, capacitive and dynamic* loads up to the following maxi- mums are safe: CAPACITIVE LOAD Bon oo rN @ noo a o oon o w OUTPUT CURRENT FROM +V OR Vg (A) iy 2 3 5 7 10 SUPPLY TO OUTPUT DIFFERENTIAL VOLTAGE Vg Vg (V) 15 20 2530 40 INDUCTIVE LOAD Ws hay = 2A hy = 5A lin = 28 lay = BA 18V 2mF 0.7mF 2H 10mH 15V 10mF 2.2mF 7H 25mH 10V 25mF 10mF 5H 50mH If the inductive load 1s driven near steady state conditions, allowing the output voltage to drop more than 8V below the supply rail with IL, = 5A, or 17V below the supply rail with In, = 2A while the amplifier is current limiting, the inductor should be capacitively coupled or the current limit must be lowered to meet SOA criteria. 2. The amplifier can handie any EMF generating or reactive load and short circuits to the supply rails or shorts to common if the current limits are set as follows at T, = 85C. SHORT TO +V. SHORT TO +V, C, LOR EMF LOAD COMMON 18V BA 1.7A 15V 7A 2.8A 10V 1.6A 4.24 These simplified limits may be exceeded with further analysis using the operating conditions for a specific application. CURRENT LIMIT Proper operation requires the use of two current limit resistors, connected as shown in the external connection diagram. The minimum value for R,, is 0.12 ohm, however for optimum reliability it should be set as high as possible. Refer to the General Operating Considerations section of the handbook for current limit adjust details. DEVICE MOUNTING The case (mounting flange) is electrically isolated and should be mounted directly to a heatsink with thermal compound. Screws with Belville spring washers are recom- mended to maintain positive clamping pressure on heatsink mounting surfaces. Long periods of thermal cycling can loosen mounting screws and increase thermai resis- tance. Since the case is electrically isolated (floating) with respect to the internal circuits it is recommended to connect it to common or other convenient AC ground potential. C46 PAQWU REV.
