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 12...
