FEATURES
Mono 2.9 W Class-D Audio Amplifier with Digital Current and Voltage Output SSM4321
The SSM4321 features a high efficiency, low noise modulation scheme that requires no external LC output filters.

The modulation scheme provides high efficiency even at low output power. The SSM4321 operates with 89% efficiency at 1.4 W into 8 from a 5.0 V supply with an SNR of >100 dB. The SSM4321 includes circuitry to sense output current, output voltage, and the PVDD supply voltage. Current sense is performed using an external sense resistor that is connected between an output pin and the load. The output current and voltage are sent to ADCs with 16-bit resolution; the PVDD supply voltage is sent to an ADC with 8-bit resolution. The outputs of these ADCs are available on the TDM or I2S output serial port. The SLOT pin is used to determine which of four possible output slots is used on the TDM interface. A stereo I2S interface can be selected by reversing the pin connections for BC
