Gains of 0 dB, ±3 dB, and ±6 dB are available to suit various applications requirements. These devices are 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. All three versions of the part typically exhibit 90 dB of common-mode rejection. With 15 V/μs slew rate, 7.6 MHz or higher bandwidth, and 0.0006% THD, these devices are sonically transparent. Moreover, current consumption is typically a low 6 mA (3 mA per amplifier). The 1280 series is available in a 14-pin SOIC package. The 1280 is pin-compatible with the TI INA2134, and the 1286 is pin-compatible with the TI INA2137 and the ADI AD8273.

Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only; the functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not impli ed. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 4. 0 dBu = 0.775 Vrms. 5. While specific resistor ratios are very closely trimmed, absolute resistance values can vary ±25% from the typical values show n. Input impedance is monitored by lot sampling. 6.
