Description
The THAT 1280 series of precision differen-
tial 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 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 trans-
parent. 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.
