VGA001
Variable Gain Amplifier
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)
