TEXAS INSTRUMENTS PGA2500IDBG4 音频功率放大器, AB, 1通道, ± 4.75V 至 ± 5.25V, SSOP, 28 引脚
The is a digitally controlled analog Microphone Preamplifier designed for use as a front end for high performance audio analog-to-digital A/D converters. 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 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.
