The PGA2500IDB from Texas Instruments is a digitally controlled analog microphone preamplifier designed for high-performance audio analog-to-digital converter front ends. It features a fully differential input-to-output architecture, contributing to its low noise and wide dynamic range.
The gain is digitally controlled via a serial port interface, with a range from 0dB up to 65dB in 1dB steps. Dynamic performance includes an equivalent noise of -128dBu with a source impedance of 150Ω and a gain of 30dB, and a Total Harmonic Distortion plus Noise (THD+N) of 0.0004% at the same gain setting. Features like zero-crossing detection minimize audible artifacts during gain switching, and an integrated DC servo minimizes output offset voltage.
This device operates over an industrial temperature range of -40°C to 85°C and requires ±5V power supplies. It is available in an SSOP-28 package. The PGA2500IDB is suitable for applications such as microphone preamplifiers and mixers, and digital mixers and recorders.
The gain range is 0dB, and 10dB to 65dB in 1dB steps.
The operating temperature range is -40°C to 85°C.
It requires ±5V power supplies.
The THD+N is 0.0004% when the gain is set to 30dB.
The equivalent noise is -128dBu with a source impedance of 150Ω and a gain of 30dB.
The PGA2500IDB is available in an SSOP-28 package.
