THAT 1280 精密差分放大器主要用作音频应用的平衡线路接收器,并提供 0 dB 的增益。

该器件以晶圆形式进行激光微调,以获得高 CMR 性能和精确增益所需的精确电阻匹配。

1280 采用 THAT Corporation 专有的互补电介质隔离 (DI) 工艺制造,提供分立设计的声音优势以及完全集成解决方案的简单性、可靠性、匹配性和小尺寸。

1280 通常表现出 90 dB 的共模抑制。该器件具有 15 V/us 压摆率、7.6 MHz 或更高带宽和 0.0006% THD,声音透明。此外,电流消耗通常只有 6 mA(每个放大器 3 mA)。

1280 采用 14 引脚 SOIC 封装,与 TI INA2134 引脚兼容。

The THAT 1280 precision differential amplifiers are designed primarily for use as a balanced line receivers for audio applications and provides a gain of 0 dB.

The device is 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 provides the sonic benefits of discrete designs with the simplicity,reliability, matching, and small size of a fully integrated solution.

The 1280 typically exhibits a 90 dB of common-mode rejection. With 15 V/us slew rate, 7.6 MHz or higher bandwidth, and 0.0006% THD, this device is sonically transparent. Additionally, current consumption is typically a low 6 mA (3 mA per amplifier).

The 1280 is available in a 14-pin SOIC package and is pin-compatible with the TI INA2134.
