Description

The TPA2054D4 features a stereo Class-D power amplifier along with a stereo DirectPath™ headphone amplifier. The TPA2054D4 has a mono differential input and two stereo single-ended (SE) inputs that can be configured as one stereo differential input. Both input channels have a 32-step volume control and the DirectPath headphone amplifier has a 4-level gain control for coarse volume adjustment. All amplifiers have output short-circuit and thermal- overload protection.

The Class-D amplifiers deliver 1.25 W into 8 at 1% THD from a 5.0 V supply, and 700 mW from 3.6 V. The DirectPath headphone amplifier features an output voltage limiter to reduce the maximum output power to one of seven possible limits. The voltage limiter is programmed through the I2C interface.
