The TPA2012D2 is a stereo, filterless Class D audioamplifier (Class D amplifier) in WCSP, QFN, or service packages. The TPA2012D2 requires only two external components for operation.

The TPA2012D2 features independent shutdown control for each channel. Gains of 6, 12, 18, or 24 dB can be selected using the gain select pins of G0 and G1. High PSRR and differential structures provide more immunity, noise, and RF rectification. In addition to these features, the fast start-up time and small package size make the TPA2012D2 Class D amplifier ideal for mobile phones and PDAs.

The TPA2012D2 is 1.4 W power drive capability / 5 V or 720 MW channel/channel at 3.6 V to 8 Ω. The TPA2012D2 is also driver 4a3A9能力.
