1280 Series Basic Application Circuit

DESCRIPTION

The THAT 1280-series of precision differential amplifiers are designed primarily for use as audio balanced line receivers. Fabricated using THAT’s proprietary DI process, the THAT 1286 is drop-in compatible with the TI INA2137, while the THAT 1280 is pin compatible with the INA2134 and the Analog Devices AD8273.

The parts are available in models which can be configured as differential amplifiers for 0dB, +/-3dB, and +/-6dB gain. The internal precision-trimmed thin film resistors enable a wide variety of circuits that are virtually impossible to build with discrete components.
