DESCRIPTION
The PGA2500 is a digitally controlled, analog microphone
preamplifier designed for use as a front end for high-
performance audio analog-to-digital converters (ADCs). The
PGA2500 features include low noise, wide dynamic range,
and a differential signal path. An on-chip DC servo loop is
employed to minimize DC offset, while a common-mode
servo function may be used to enhance common-mode
rejection.
The PGA2500 features a gain range of 10dB through 65dB
(1dB/step), along with a unity gain setting. The wide gain
range allows the PGA2500 to be used with a variety of
microphones. Gain settings and internal functions are
programmed using a 16-bit control word, which is loaded
using a simple serial port interface. A serial data output pin
provides support for daisy-chained connection of multiple
PGA2500 devices. Four programmable digital outputs are
provided for controlling the external switching of input pads,
phantom power, high pass filters, and polarity reversal
functions. The PGA2500 requires both +5V and −5V power
supplies and is available in a small SSOP-28 package.
