).
• HIGH GAIN ACCURACY: 20dB ± 0.3dB
The VCA822 internal architecture consists of two
• HIGH OUTPUT CURRENT: ± 160mA
input buffers and an output current feedback amplifier
stage integrated with a multiplier core to provide a
complete variable gain amplifier (VGA) system that

gain is set externally with two resistors, providing
flexibility in designs. The maximum gain is intended

voltage varies from +1V to – 1V. For example, set for
a maximum gain of +10V/V, the VCA822 provides
10V/V, at +1V input, to 0.1V/V at – 1V input of gain
control range. The VCA822 offers excellent gain
linearity. For a 20dB maximum gain, and a
gain-control input voltage varying between 0V and
1V, the gain does not deviate by more than ± 0.3dB
(maximum at +25 ° C).
