1. Overview & Function:

️· Type: Mono, Class D audio amplifier.
️· Key Features:
- Anti-pop circuitry for clean power-up and shut-down.
- Short-circuit protection (SCP).
- Over-temperature protection (OTP).
- Shutdown mode for reduced power consumption.
- Adjustable gain for flexible use.

2. Electrical Characteristics & Performance:

️· Designed for 2.0 Watts of output power.
️· Operates on a supply voltage.
️· Low distortion (THD).
️· Flat bass response down to 150Hz.

3. Design & Layout Considerations (Critical for Optimal Performance):

️· Grounding: Essential to use plane grounding and separate grounds for signal and power.
️· Decoupling Capacitors: Use both high-frequency (1µF) ceramic and bulk (10µF) capacitors near the power supply pins (VDD).
️· Component Placement: Keep input resistors/caps close to input pins, and the ferrite EMI filter close to the output pins.
️· Power Line: Short and wide traces for the power line to minimize noise.

4. Ordering Information & Packages:

️· Package Options:
- WCSP9 (Wafer-Level Chip Scale Package - 1.3mm x 1.3mm)
- eMSOP10 (eMSOP - extended small outline package)
️· Part Numbers: (See table in documentation). Marking codes are also provided.

5. Protection Features

️· Shutdown Mode: Reduces power consumption when inactive.
️· Short-Circuit Protection: Prevents damage from shorted outputs.
️· Over-Temperature Protection: Protects the device from overheating.

6. Key Design Guidelines:

️· Input Capacitors: Need to be carefully selected, considering leakage currents, and polarity.
️· Ferrite Bead: Essential for EMI reduction.
️· Power Supply: Power supply traces should be short and thick
