Precision Voltage-Controlled Amplifier
High Gain Adjust Range, Wide Bandwidth
("A" version indicates the higher grade part)
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. Increasing the control voltage above ground will attenuate the signal path to > 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.
HIGH GAIN ADJUST RANGE: +/-40dB
DIFFERENTIAL IN/SINGLE-ENDED OUT
LOW INPUT NOISE VOLTAGE: 2.4nV/vHz
