Product Summary
The msc1157ms-kr3, 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 msc1157ms-kr3, because of its ability to stand by, is ideally suitable for portable equipment applications powered by a battery.
