详细描述

THAT2181 压控放大器 (VCA) 是一款高性能电流输入/电流输出设备，具有两个相反极性的电压敏感控制端口。

它以较低的信号失真提供增益和衰减的大范围指数控制。

零件是在封装后选择的，选择主要基于调整后的 THD 和控制电压馈通性能。

VCA 设计利用完全互补的介电隔离工艺，提供紧密匹配的 NPN/PNP 对。这提供了通过任何传统工艺，无论是集成的还是离散的，都无法获得的性能。

该部件可由用户调整至最低 0.005% THD，允许用户优化成本和性能。

演示板 THAT2181DEMO 可用于该产品。

The THAT2181 voltage controlled amplifier(VCA) is a high performance current in/current out device with two opposing polarity, voltage sensitive control ports.

It offers wide range exponential control of gain and attenuation with lower signal distortion.

The parts are selected after packaging and the selection is based primarily on after-trim THD and control voltage feedthrough performance.

The VCA design takes advantage of a fully complementary dielectric isolation process which offers closely matched NPN/PNP pairs. This delivers performance unobtainable through any conventional process, integrated or discrete.

The part is user trimmable to a minimum of 0.005% THD allowing the user to optimise cost and performance.

Demonstration Board THAT2181DEMO is available for this product.
