The Texas Instruments TPA0232PWPR is a 2.8-W/Ch stereo audio power amplifier designed for PC audio applications. It is compatible with PC 99 desktop and portable standards, delivering 1W into 10-kΩ and 8-Ω loads respectively. The amplifier integrates internal gain control, eliminating the need for external gain-setting resistors, and offers DC volume control ranging from 20 dB to -40 dB in 31 discrete steps.
This device minimizes external component count, simplifying design and saving board space. It includes integrated depop circuitry to prevent speaker noise during power-up and shutdown. The TPA0232PWPR features an input MUX for selecting between two sets of stereo inputs and supports both single-ended (SE) and bridge-tied load (BTL) modes. It operates with low supply current during normal operation and a miserly shutdown current.
The amplifier is housed in a 24-pin TSSOP PowerPAD package, providing excellent thermal performance. This allows it to operate at full power into 8-Ω loads at ambient temperatures up to 85°C. The compact size and thermal management make it suitable for space-constrained designs.
2.8W per channel continuous RMS into a 3Ω load, and 1W into 10kΩ or 8Ω loads.
Less than 0.4% THD+N at 1W output into 8Ω speakers.
The DC volume control ranges from 20dB to -40dB in 31 discrete steps.
Typical supply current is 10mA during normal operation and 150µA in shutdown mode.
The thermal impedance is approximately 35°C/W.
It is available in a PWP TSSOP surface mount package.
