Description

The TPA2012D2 is a stereo, filter-free, Class-D audioamplifier (class-D amp) available in a WCSP, QFN, or PWP package. The TPA2012D2 only requires two external components for operation.

The TPA2012D2 features independent shutdown controls for each channel. The gain can be selected to 6, 12, 18, or 24 dB utilizing the G0 and G1 gain select pins. High PSRR and differential architecture provide increased immunity to noise and RF rectification. In addition to these features, a fast startup time and small package size make the TPA2012D2 class-D amp an ideal choice for both cellular handsets and PDAs.

The TPA2012D2 is capable of driving 1.4 W/Ch at 5 V or 720 mW/Ch at 3.6 V into 8 Ω. The TPA2012D2 is also capable of driving 4 &#a3A9;. The TPA2012D2 is thermally limited in WCSP and may not achieve 2.1 W/Ch for 4 Ω. The maximum output power in the WCSP is determined by the ability of the circuit board to remove heat. The output power versus load resistance graph below shows thermally limited region of the WCSP in relation to the QFN package. The TPA2012D2 provides thermal and short circuit protection.
