TPA2054D4A

The TPA2054D4A features a stereo Class-D power amplifier along with a stereo DirectPath™ headphone amplifier. The TPA2054D4A 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.

Features of the TPA2054D4A are:(1)Stereo Class-D Amp: 1.4 W into 8 ? from 5.0 V (10% THD + N) 1.25 W into 8 ? from 5.0 V (1% THD + N); (2)DirectPath? Stereo Headphone Amplifier No Output Capacitors Required; (3)Independent Gain Select for Headphone Amplifier; (4)Eight Programmable Maximum Headphone Voltage Limits; (5)Two Single-Ended or One Differential Stereo Input; (6)3:1 Input MUX with Mode Control; (7)32-Step Volume Control for Both Input Channels; (8)Independent Shutdown for Headphone and Class-D Amplifiers; (9)Short-Circuit and Thermal-Overload Protection; (10)±8 kV HBM ESD Protection on Headphone Outputs; (11)I2C Interface; (12)25-Ball 2,61 mm * 2,61 mm WCSP.

The absolute maximum ratings of the TPA2054D4A can be summarized as:(1)Operating free-air temperature range :40 to 85 °C; (2)Operating junction temperature range :40 to 150 °C; (3)Storage temperature range :65 to 150 °C.
