SLOS442A – MAY 2005 – REVISED JULY 2005
20-W MONO DIGITAL INPUT AUDIO AMPLIFIER
FEATURES
Digital Interface
– 24-bit Resolution
– Supports I2S and 16-Bit Word
Right-Justified Digital Input Formats
– Multiple Sampling Frequencies:
5 kHz – 200 kHz
– 8x Oversampling Digital Filter
– Soft Mute
Power Amplifier
– 20-W into an 8-Load from an 18-V Supply
– Efficient Operation Eliminates Need for Heat
Sinks
– Three Selectable, Fixed Gain Settings
– Thermal and Short-Circuit Protection
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 . 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.
