DESCRIPTION

INA110

FET

Input

–In

The INA110 is a versatile monolithic FET-input

instrumentation amplifier. Its current-feedback circuit

topology and laser trimmed input stage provide

excellent dynamic performance and accuracy. The

INA110 settles in 4µs to 0.01%, making it ideal for

high speed or multiplexed-input data acquisition

systems.
