DESCRIPTION
 

The THAT 1510 and 1512 are high performance current-feedback instrumentation amplifiers designed for low source-impedance preamp and bus summing applications. The ICs are available in a variety of packages and pin configurations, making them pin compatible with the Analog Devices SSM2019 and SSM2017 (discontinued), and the Texas Instruments INA217 and INA163.

The parts are designed from the ground up in THAT’s complementary dielectric isolation process and include on-chip laser-trimmed Si-Chrome thin film resistor. In microphone preamplifier applications, both the 1510 and 1512 improve on previous integrated designs by offering lower noise at low gains, wider bandwidth, higher slew rate, lower distortion, and lower supply current.

描述
即1510和1512的高性能电流反馈的仪表放大器设计用于低源阻抗前置总线和总结应用。ICS在各种封装和引脚配置，使其销与模拟设备SSM2019和SSM2017（已停产），兼容和德克萨斯仪器ina217和ina163。

这些部分是从互补绝缘隔离工艺的基础上设计的，包括片上激光修整的硅铬薄膜电阻器。在麦克风前置放大器应用中，1510和1512改进了以前的集成设计，通过提供低噪声、低增益、更宽的带宽、更高的转换速率、更低的失真和更低的电源电流
