    1250 Series Basic Application Circuit

    DESCRIPTION

    The low-cost THAT 1250-series of precision differential amplifiers are designed primarily for use as audio balanced line receivers. Fabricated using THAT’s proprietary DI process, the THAT 1256 is pin compatible with the THAT 1246. the Texas Instruments INA137, and Analog Devices SSM2143, while the THAT 1250 is pin compatible with the 1246, INA134, and SSM2141. The THAT 1253 is pin-compatible with the 1243. The parts are available in models which can be configured as differential amplifiers for 0dB, +/-3dB, and +/-6dB gain.

    The 1250-series achieves its low cost by eliminating laser trimming compared to its pin-compatible relations. As a result, the 1250-seriues offers less common mode rejection and precision in its resistor ratios compared to the 1240-series (and equivalents from other manufacturers).filler
