Datasheet
Mono Bridge-Tied Load Class-D amplifier at port-H (MONO-OUT) has 2Watt (rms) power for 4Ω
load speaker
Short circuit and over current protection for Class-D amplifier
Class-D amplifier has high pass filter with selectable Cut-Off frequency to prevent low frequency
signal damaging speaker
Class-D amplifier output with slew rate and spread spectrum control to reduce EMI radiation
Intel low power ECR HDA015-B compliant: supports power status control, jack detection, and
wake-up event in D3 mode
Two GPIOs for customized applications
EAPD (External Amplifier Power Down) is supported
Supports anti-pop mode when analog power AVDD is on and digital power is off
PCBEEP pass through to MONO-OUT port (Class-D amplifier) in anti-pop mode
Built-in 5V-to-4.5V LDO to power analog circuitry
Power support: 3.3V digital core power; 1.5V~3.3V digital IO power for HDA link; 4.5V~5.5V
analog power; 4.5V~5.5V power stage voltage
48-pin QFN ‘Green’ package
