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.
