詳細(xì)描述

THAT2181 壓控放大器 (VCA) 是一款高性能電流輸入/電流輸出設(shè)備，具有兩個(gè)相反極性的電壓敏感控制端口。

它以較低的信號(hào)失真提供增益和衰減的大范圍指數(shù)控制。

零件是在封裝后選擇的，選擇主要基于調(diào)整后的 THD 和控制電壓饋通性能。

VCA 設(shè)計(jì)利用互補(bǔ)的介電隔離工藝，提供緊密匹配的 NPN/PNP 對(duì)。這提供了通過任何傳統(tǒng)工藝，無論是集成的還是離散的，都無法獲得的性能。

該部件可由用戶調(diào)整至 0.005% THD，允許用戶優(yōu)化成本和性能。

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.
