DESCRIPTION
The TPA2012D2 is a stereo, filter-free, Class-D
audio amplifier (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.
