VCA810ID Datasheet PDF - TI

●The VCA810ID is a Wideband Voltage-controlled Amplifier that provides a differential input to single-ended output conversion with a high-impedance gain control input used to vary the gain over a -40 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. Increasing the control voltage above ground will attenuate the signal path to greater than 80dB. Signal bandwidth and slew rate remain constant over the entire gain adjust range. This 40dB/V gain control is accurate within ±1.5dB (±0.9dB for high grade), allowing the gain control voltage in an AGC application to be used as a Received Signal Strength Indicator (RSSI) with ±1.5dB accuracy. Excellent common-mode rejection and common-mode input range at the two high-impedance inputs allow the VCA810 to provide a differential receiver operation with gain adjust.
