Cirrus Logic, Inc. Linear - Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps - PA79DK PA79DK

The PA79DK is a high voltage, high speed operational amplifier designed for applications requiring low idle current and high output capabilities. It features a unique technique for achieving very low quiescent current, consuming less than 1mA while delivering up to 200mA peak output current. The amplifier boasts a slew rate exceeding 350 V/µs and supports a wide supply voltage range, from 20V to 350V for single supply configurations and ±10V to ±175V for split supplies. With a power bandwidth of over 200 kHz and a dissipation capability of up to 26 watts in dual configurations, the PA79DK is suitable for demanding applications such as piezoelectric positioning, electrostatic deflection, and deformable mirror actuators. The output stage includes a user-selectable current limit resistor for added protection, and external phase compensation allows for optimization of bandwidth and stability. Proper heatsinking is necessary for reliable operation. The device is packaged in a 20-pin PSOP format and has a moisture sensitivity level of 3.
