• THAT1240 "0dB" Unity Gain Line Receiver, DIP
The THAT 1240-series of precision differential amplifiers are designed primarily for use as audio balanced line receivers. Fabricated using THAT’s proprietary DI process, the THAT 1246 is drop-in compatible with the TI INA137 and Analog Devices SSM2143, while the THAT 1240 is pin compatible with the INA134 and the SSM2141. 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.
