TPA3132D2RHBR Description

Short technical summary and product information.

The TPA3132D2RHBR from Texas Instruments is an analog input, Class-D audio amplifier designed for home audio, haptics, and piezo applications. It supports stereo configurations with up to 25W output power into an 8-ohm load at 19V, or mono configurations up to 50W.

This amplifier operates over a wide supply voltage range of 4.5V to 26V, making it versatile for various power requirements. It boasts high efficiency, exceeding 90%, with low idle loss, potentially eliminating the need for a heatsink. The device features advanced modulation schemes and multiple switching frequencies, including AM avoidance and master/slave synchronization, with frequencies up to 1.2MHz.

Key electrical characteristics include a minimum load impedance of 2 ohms and a typical RDS(on) of 0.12 ohms. The THD + N at 1 kHz is kept below 0.1%. It operates within an ambient temperature range of -40°C to 85°C.

The TPA3132D2RHBR is housed in a 32-pin VQFN package measuring 5mm x 5mm, designed for surface mounting. It includes integrated self-protection circuits for overvoltage, undervoltage, overtemperature, DC-detect, and short circuits with error reporting.
