VCA810 Texas Instruments (TI) is aamplifier that withbroadband, low offset voltage, voltage controlled continuously variable gain , and it can provide a differential input and a single-ended output, also has excellent common-mode rejection ratio, and the most prominent advantage is VCA810 to achieve linear gain control -40dB ~ 40dB of gain and the control accuracyis ± 1.5dB. When the Gain control voltage is from 0V to -2V( ± 5 VSupply), gain changes linearly from -40dB to + 40dB. VCA810 Have manyapplicationsin the optical receiver time gain control, sonar systems, voltage tunable active filter, logarithmic amplifiers, pulse amplitude compensation, with a wide range of AGC RSSI receiver,ect. VariableGain: -40dB to 40dB GAIN Voltage Range: 0 to -2V Input Power Rang: -6.5V to +6.5VSize: 43mm X 33mmInterface
