THAT 1250-series Low-cost Balanced Line Receiver ICs

The THAT 1250-series of precision differential amplifiers was designed primarily for use as balanced line receivers for audio applications. Gains of 0 db, ±3 dB, and ±6 dB are available to suit various applications requirements.

These devices include on-board precision thin film resistors which offer good matching and excellent tracking due to their monolithic construction. Manufactured in THAT Corporation’s proprietary complementary dielectric isolation (DI) process, the THAT 1250-series provides the sonic benefits of discrete designs with the simplicity, reliability, matching and small size of an integrated solution.

All three versions of the part typically exhibit 50 dB of common-mode rejection. With 12 V/µs slew rate, >8.6 MHz bandwidth, and 0.0006% THD, these devices are sonically transparent. Moreover, current consumption is typically a low 2 mA. Both surface-mount and DIP packages are available.

The THAT 1256 is pin-compatible with the TI INA137 and Analog Devices SSM2143, while the THAT 1250 is pin-compatible with the TI INA134 and Analog Devices SSM2141.
