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 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 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 separate 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 building block in a number of applications where noise performance is critical. The VCA2614 is available in a TQFP-32 package.
