AV2722 - AUDIO CODEC WITH HEADPHONE DRIVER AND PROGRAMMABLE SAMPLE RATES

Description

The AV2722 is a mixed signal CMOS monolithic device which is a low cost audio CODEC designed with a built-in headphone driver.

It supports regular audio or USB mode audio and is therefore ideal for portable MP3 audio and speech players and recorders.

It can also be used for minidisk, CD-RW machines.

Features

  • Complete DAC and ADC Audio CODEC with headphone driver.
  • Up to 96kHz input sampling frequencies for ADC/DAC.
  • Selectable DAC De-emphasis Filter.
  • Selectable ADC High Pass Filter.
  • Programmable Audio Data Interface.
  • I2S, Normal, Left justified or DSP data for ADC/DAC.
  • 16,18, 20 and 24-bit input data resolution.
  • System clock: 64fs, 96fs,128fs, 192fs, 256fs or 384fs.
  • 250fs and 272fs system clock for USB.
