The PGA2500 is a digitally controlled, analog microphone preamplifier designed for use as a front end for highperformance 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 mini • Fully Differential Input-to-Output Architecture\n• Digitally Controlled Gain Using Serial Port Interface: \n• Gain Range: 10dB through 65dB, 1dB per step\n• Unity (0dB) Gain Setting via Serial Port or Dedicated Control Pin\n \n• Dynamic Performance: \n• Equivalent Noise with ZS = 150 and Gain = 30;
