VCA810 Overview
The VCA810 is a DC-coupled, wideband, continuously variable, voltage-controlled gain amplifier. It provides a differential input to single-ended output conversion with a high-impedance gain control input used to vary the gain over a 40dB to +40dB range linear in dB/V. Operating from ±5V supplies, the gain control voltage for the VCA810 will adjust the gain from 40dB at 0V input to +40dB at 2V input.
