VCA2619 SBOS276A − AUGUST 2003 − REVISED AUGUST 2003 Dual, Variable Gain Amplifier with Input Buffer FEATURES D GAIN RANGE: 50dB D LOW CROSSTALK: -60dB at Max Gain, fIN = 5MHz DESCRIPTION The VCA2619 is a highly integrated, dual receive channel, Variable Gain Amplifier (VGA) with analog gain control.
The VCA2619s VGA section consists of two parts: the Voltage Controlled Attenuator (VCA) and the Programmable Gain Amplifier (PGA).
The gain and gain range of the PGA can be digitally programmed.
The combination of these two programmable elements results in a variable gain ranging from 0dB up to a maximum gain as defined by the user through external connections.
The single−ended unity gain inpu...
