Overview
The TPDA7008 is a high-performance converter that converts Pulse Density Modulation (PDM) input streams to one Pulse Code Modulation(PCM) output stream. And the audio PCM data can be sent through the serial audio interface of Time Division Multiplexing (TDM) or I2S. The PDM data can be from up to eight digital microphones or other PDM sources.
The TPDA7008 features some advanced integrated designs of programmable channel gain and phase, highpass filter (HPF), bi-quad filters, and low-latency filters that improve audio performance. With these excellent performance functions, the TPDA7008 becomes a suitable choice of hardware peripheral in entire audio systems, particularly in far-field microphone arrays for voice acquisition and algorithm processing.
