THAT2181B - Voltage Controlled Amplifiers

Download the THAT2181B datasheet PDF. This datasheet also covers the THAT2181A variant, as both devices belong to the same voltage controlled amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

THAT 2181 Series integrated-circuit voltage controlled amplifiers (VCAs) are very highperformance current-in/current-out devices with two opposing-polarity, voltage-sensitive control ports.

They offer wide-range exponential control of gain and attenuation with low signal distortion.

Key Features

  • Wide Dynamic Range: >120 dB.
  • Wide Gain Range: >130 dB.
  • Exponential (dB) Gain Control.
  • Low Distortion: ~ 0.0025 % (typical 2181A) ~ 0.005 % (typical 2181C).
  • Wide Gain-Bandwidth: 20 MHz.
  • Dual Gain-Control Ports (pos/neg).
  • Pin-Compatible with 2150-Series Blackmer® Trimmable IC Voltage Controlled Amplifiers THAT 2181A, 2181B, 2181C.
