This circuit increases both the output current and the voltage-swing capability for a typical IC amplifier. The transistors run in the Zener mode, dropping the supply to about±7 V at the LTC1052. The LT318A serves as an output stage with a voltage gain of 4. The output swing is typically±13 V into 2 kΩ, with a short-circuit current of 20 mA. The circuit is dynamically stable at any gain, either inverting or noninverting. However, the LTC1052 input common-mode range (-7 V to +5 V with the ±15-V supply) must not be exceeded.
