CMOS IC
Monaural CODEC+Audio I/F +Video driver IC
Overview
The LC074146LP is an IC that integrates a video driver with audio CODEC developed for digital still cameras and other
portable equipment. Incorporating 16-bit A/D and D/A converters as well as a microphone amplifier and speaker driver
that are necessary for audio recording and playback, the one-chip IC is ideal for use to create audio interfaces.
