Variable Gain Amplifier

VGA001

100Hz - 100MHz Variable Gain Amplifier

Fully differential input and output

Can be used as single-ended input to differential output

3.3V Supply

•

Designed in C3N (0.35µ) process (See General Notes 1)

1.0 Description

The VGA001 is a voltage controlled Variable Gain Amplifier. It was designed for a maximum input signal of 600uV over a bandwidth

of 100Hz to 100MHz. A control voltage must be provided to set the gain, and the typical range is –3dB to 17dB. Additional

circuitry can be used to control the common mode voltage of the differential output. The current required for the common mode

adjustment circuitry varies depending on the desired voltage level. (3)
