NEGATIVE OUTPUT OVERLOAD RESPONSE TIME Applications Information V+ Functional Description The ISL28177 is a low noise op amp fabricated in a 40V complementary bipolar DI process designed for general purpose low power applications. It utilizes a super-beta NPN input stage with input bias current cancellation for low input bias current and low input noise voltage. A complimentary bipolar output stage enables high capacitive load drive without external compensation. Operating Voltage Range The ISL28177 is designed to operate over the 6V (±3V) to 40V (±20V) range. The common mode input voltage range extends to 2V from each rail, and the output voltage swings to 1.3V of each rail. Input Performance The super-beta NPN input pair reduces input bias current while maintaining good frequency response, low input bias current and low noise. Input bias cancellation circuits provide additional bias current reduction to
