GENERAL DESCRIPTION
The ADAU1513 is a 2-channel bridge-tied load (BTL)
Class-D audio power stage. The power stage can drive the
speaker loads of 4 Ω at up to 15 W per channel at high
efficiency. The 4-channel audio system can be formed when
used with an ADAV4201 pulse-width modulator (PWM)
processor using two ADAU1513s. The power stage accepts a
3.3 V logic differential PWM as input from an ADAV4201
processor. The power stage comprises thermal and output
short-circuit protection with logic-level error flag outputs for
interfacing to a system microcontroller along with reset and
mute control of the power stage. The power stage operates from
a range of power supply voltages from 9 V up to 18 V. The low
power digital logic operates from a 3.3 V supply. The power
stage can be used with modulators other than the ADAV4201.
