AN7515SH
Audio signal processing IC for notebook PC
I Overview
AN7515SH has a speaker power amplifier, head-
phone power amplifier, line amplifier, electric vol-
ume and a bass boost circuit for notebook PC. This
IC adopts a small thin package, enabling compact
and high integrated set.
I Features
Possible speaker power is
1 W
2-ch.
: 8
output at V
CC
= 5 V
0.65 W
2-ch.: 4 output at V
CC
= 3.3 V
A gain and frequency response of bass boost can
be adjusted with external components
Each amplifiers has a standby and mute switch
Pin compatible with AN7516SH with Spatializer
function except for Spatializer pins
V
CC
of speaker and headphone can be adjusted
separately
