VCA2614
Dual, VARIABLE GAIN AMPLIFIER
with Input Buffer
DESCRIPTION
The VCA2614 is a highly integrated, dual receive channel,
Variable Gain Amplifier (VGA) with analog gain control.
The VCA2614’s VGA section consists of two parts: the Volt-
age 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 program-
mable 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 input buffer provides
predictable high input impedance. The output of the VGA can
be used in either a single-ended or differential mode to drive
high-performance Analog-to-Digital Converters (ADCs). A sepa-
rate power-down pin reduces power consumption.
The VCA2614 also features low crosstalk and outstanding
distortion performance. The combination of low noise and gain
range programmability makes the VCA2614 a versatile build-
ing block in a number of applications where noise perfor-
mance is critical. The VCA2614 is available in a TQFP-32
package.
