MSC1157 Speaker Drive Amplifier

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 coupl.
