TPA2012D2 Description

Short technical summary and product information.

The TPA2012D2 from Texas Instruments is a stereo, filter-free, Class-D audio amplifier designed for a wide range of portable applications. It requires only two external components for operation and features independent shutdown controls for each channel.

Key electrical specifications include a power supply range of 2.5 V to 5.5 V. The amplifier can deliver up to 2.1 W/Channel into a 4 Ω load at 5 V (WQFN package) or 1.2 W/Channel into 4 Ω at 5 V (DSBGA package, thermally limited). Selectable gain settings of 6, 12, 18, and 24 dB are available. It also boasts a high PSRR of 77 dB at 217 Hz and a fast start-up time of 3.5 ms.

The TPA2012D2 is available in space-saving packages: a 2.01-mm x 2.01-mm NanoFree™ DSBGA and a 4-mm x 4-mm Thin WQFN with PowerPAD™. These compact footprints make it suitable for integration into mobile phones, PDAs, portable DVD players, and notebook PCs.

Additional features include internal pulldown resistors on shutdown pins, short-circuit protection, and thermal protection, enhancing its reliability in demanding applications.
