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 singleended unity gain
input buffer provides predictable high input impedance. The
output of the VGA can be used in either a singleended or
differential mode to drive highperformance Analogto
Digital (A/D) converters. A separate powerdown pin
reduces power consumption.
The VCA2619 also features low crosstalk and outstanding
distortion performance. The combination of low noise and
gain range programmability make the VCA2619 a versatile
building block in a number of applications where noise
performance is critical. The VCA2619 is available in a
TQFP32 package.
