Audio signal processing IC for digital still cameras
AN12909A
Overview
Incorporating a microphone amplifier, line amplifier and
BTL power amplifier, the AN12909A functions as an ideal
audio signal processor IC for digital still cameras. This IC
features serial signal control for various mode switchovers
and separate filters for recording and playback, saving space
and reducing power consumption.
Features
• Built-in microphone power supply.
• Built-in low pass filters for playback and recording.
• Uses serial signals for various mode changes and EVR
control.
Recording filter switchover, microphone amplifier, line
mute, standby, SP output control.
• Small surface-mount package: QFN028-P-0405B.
Application
Mobile equipment including digital still cameras and PDAs
