TPA3221DDVR Description

Short technical summary and product information.

The Texas Instruments TPA3221DDVR is a high-performance Class-D audio amplifier designed for home audio applications. It delivers up to 105W stereo into a 4Ω load at 10% THD+N, and up to 208W mono into a 2Ω load. The device operates from a wide power supply range of 7V to 30V, with analog supply voltage from 5V to 30V.

Key electrical characteristics include a signal bandwidth up to 100kHz, low idle current of less than 1mA in shutdown modes, and high efficiency up to 90%. It offers selectable gains of 18dB, 24dB, 30dB, and 34dB, and supports differential or single-ended analog inputs. Integrated protection features include undervoltage, current limit, short circuit, clipping detection, and thermal shutdown.

The TPA3221DDVR is available in a 44-pin HTSSOP package with a thermal pad. Its pin-compatible family offers various voltage and power level options for design flexibility. This amplifier is suitable for speaker, TV, and soundbar audio applications requiring high-fidelity sound reproduction.
