TPA2012D2YZHR Description

Short technical summary and product information.

The Texas Instruments TPA2012D2YZHR is a 2.1-W/channel stereo, filter-free, Class-D audio power amplifier. It features an analog input and is designed for mobile phone, tablet, and wearable audio applications. The amplifier operates over a wide power supply range of 2.5 V to 5.5 V, with selectable gain options of 6, 12, 18, and 24 dB.

Key electrical characteristics include a THD + N of 0.14% at 1 kHz and a minimum load impedance of 4 Ω. The device offers independent shutdown control for each channel, high PSRR of 77 dB at 217 Hz, and a fast start-up time of 3.5 ms. It also includes short-circuit and thermal protection.

The TPA2012D2YZHR is available in space-saving WQFN (4 mm x 4 mm) and DSBGA (2.01 mm x 2.01 mm) packages. It requires only two external components for operation, simplifying design and reducing board space. The operating temperature range is -40 °C to 85 °C.
