Pre-amplifier accepts analog signals from the ECM and drives an over-sampled sigma delta ADC and outputs Pulse Density Modulation (PDM) data streams.
The 'Digital' is a single bit, Pulse Density Modulation (PDM) device, has an integrated sleep mode, and is compatible with stereo input applications.
While most Class-D amplifiers use some variation of pulse-width modulation (PWM), ADI's Class-D amplifiers use a sigma-delta pulse density modulation (PDM) to reduce the amplitude of spectral components at high-frequencies, thus significantly minimizing EMI emissions.
