DESCRIPTION

The TPA3200D1 is a 20-W (per channel) efficient,

digital audio power amplifier for driving a bridged-tied

speaker. The TPA3200D1 can drive a speaker with

an impedance as low as 4

鈩?

The high efficiency of

the TPA3200D1 (85%) eliminates the need for an

external heat sink.

The digital input accepts 16-24 bit data in I

S format

or 16-bit word right-justified. A digital filter performs

an 8x interpolation function. Other features include

soft mute, a zero input detect output flag for power

conscious designs, and power saving shutdown

mode.
