1286S14-U

1286S14-U is a 1280 series, dual-balanced line receiver IC. It is designed primarily for use as a balanced line receiver for audio applications. This device is laser-trimmed in wafer form to obtain the precision resistor matching needed for high CMR performance and precise gain. Manufactured in THAT Corporation’s proprietary complementary dielectric isolation (DI) process, the 1280 series provides the sonic benefits of discrete designs with the simplicity, reliability, matching, and small size of a fully integrated solution. It is used in applications such as balanced audio line receivers, instrumentation amplifiers, differential amplifiers, precision summers, and current shunt monitors.
