The TI TPA6021A4 audio amplifier evaluation module includes the following features:
• TPA6021A4 stereo 2-W audio power amplifier evaluation module
– Internal depop circuitry to minimize transients in outputs
– Dual channel, bridge-tied load (BTL) or single-ended (SE) operation
– 2 W per channel output power into 4 Ω at 5 V, BTL
– Low current consumption in shutdown mode (maximum 20 µ A)
– DC voltage volume control from 20 dB to –40 dB, and –85 dB mute (BTL Mode)
– SE dc voltage volume control proportional to BTL gain setting
– Phenolic single sided PCB board
– Differential stereo inputs
– A fade mode slowly ramps up or down the volume when coming out of or going into shutdown.
