PDM Input Class D Audio Power Amplifier
1. Product Overview
This is a digital pulse-density modulated (PDM) input Class D power amplifier with Class AB audio performance and Class D efficiency.
Active emissions-limiting, edge-rate limiting, and overshoot control circuitry greatly reduce EMI.
A filterless spread-spectrum modulation scheme eliminates the need for output filtering found in traditional Class D devices and reduces the component count of the solution.
2. Parametric Specifications
Single-Supply Operation (2.5V to 5.5V)
3W Output Power into 4¦¸ at 5V
1mA Quiescent Current
92% Efficiency (RL = 8¦¸, POUT = 900mW, VDD = 3.7V)
29uV VRMS Output Noise (AV = 6dB)
Low 0.01% THD+N at 1kHz
Exceptionally High Jitter Tolerance
Supported PDM_CLK Rates of 1.84MHz¨C4.32MHz and 5.28MHz¨C8.64MHz
Supports Left, Right, or Left/2 + Right/2 Outputs
Sophisticated Edge Rate Control Enables Filterless Class D Outputs
77dB PSRR at 217Hz
Extensive Click-and-Pop Reduction Circuitry
Robust Short-Circuit and Thermal Protection
