The TPA0103PWPR is a 3-channel audio power amplifier designed by Texas Instruments, primarily for desktop and notebook PC applications. This device features stereo single-ended (SE) channels capable of delivering 500 mW of continuous RMS power per channel into 4-ohm loads with a 3.3-V supply. It also includes a mono Bridge-Tied Load (BTL) center channel capable of 1.75 W.
The amplifier's gain is externally configurable via resistors, supporting settings from 1 to 10 without external compensation. A two-channel input multiplexer is integrated for the L/R channels, allowing for two sets of stereo inputs. The center channel amplifier can be driven from a mix of L/R inputs to create a monaural representation of the stereo signal and can be shut down independently for speaker muting.
Key electrical characteristics include an analog input type, Class-AB architecture, and support for stereo speaker channels. The device operates within an analog supply voltage range of 4.5 V to 5.5 V. It offers low distortion, with THD+N at 1 kHz typically 0.25% and output distortion below 0.05% at full power. The minimum load impedance is 4 ohms.
Packaged in a 24-pin TSSOP (PWP) surface-mount thermal package, the TPA0103PWPR is designed for efficient thermal performance. It features a full shutdown function that reduces bias current to 5 µA for power-sensitive applications. The control interface is GPIO.
