DESCRIPTION
The TAS5707 is a 20-W, efficient, digital-audio power
amplifier for driving stereo bridge-tied speakers. One
serial data input allows processing of up to two
discrete audio channels and seamless integration to
most digital audio processors and MPEG decoders.
The device accepts a wide range of input data and
data rates. A fully programmable data path routes
these channels to the internal speaker drivers.
The TAS5707 is a slave-only device receiving all
clocks from external sources. The TAS5707 operates
with a PWM carrier between a 384-kHz switching rate
and 352-KHz switching rate, depending on the input
sample rate. Oversampling combined with a
fourth-order noise shaper provides a flat noise floor
and excellent dynamic range from 20 Hz to 20 kHz..
The TAS5707A is identical in function to the HTQFP
packaged TAS5707, but has a unique I2C device
address. The address of the TAS5707 is 0x36. The
address of the TAS5707A is 0x3A.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
