PGA2505 麦克风前置放大器
pga2505 麦克风前置放大器
增益范围：0db 和 9db 至 60db，3db 步进
the pga2505 is a digitally-controlled, analog microphone preamplifier designed for use as a front-end for high-performance audio analog-to-digital converters (adcs). the pga2505 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 pga2505 features a gain range of 9db through 60db (3db/step), along with a unity gain setting. the wide gain range allows the pga2505 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 pga2505 devices. four programmable digital outputs are provided for controlling the external switching of input pads, phantom power, and high-pass filters. the pga2505 requires both +5v and -5v power supplies and is available in a small ssop-24 package.
