Speaker Drive Amplifier
GENERAL DESCRIPTION
The MSC1157, designed specifically to operate at a low voltage with low current consumption,
is a power amplifier developed for driving a speaker for a voice IC.
The voltage gains can be adjusted over a range of up to ten. The differential output can directly
drive a speaker without any output coupling capacitors. The MSC 1157, because of its ability to
stand by, is ideally suitable for portable equipment applications powered by a battery.
FEATURES
Low voltage operation
Low current dissipation
Operating current
Standby function
High output current
Differential outputs
: 2.0 to 6.0 V (Single power supply)
: 1.6mA without load (typ.)
: Current dissipation less than 1
m
A in standby
: 350mA peak
: A speaker can be directly connected between
differential outputs.
: Gain can be adjusted by use of an external resistor.
Adjustable gain
