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 O. The high efficiency of the TPA3200D1 (85%) eliminates the need for an external heat sink. The digital input accepts 16-24 bit data in I2S 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.
