AK4332ECB

Low-power HiFi D/A converter for true wireless earphones

AK4332ECB

The AK4332 is an advanced 32-bit high sound quality mono audio DAC with a built-in ground-referenced headphone amplifier. It has four types of 32-bit digital filters for better sound quality, achieving low distortion characteristics and wide dynamic range. The AK4332 accepts PCM Data, PDM Data and DSD Data. It is available in a 30-pin CSP package, utilizing less board space than competitive offerings. It is ideal for true wireless earphones, (TWS: True Wireless Stereo).

High Performance of -101dB THD+N with only 2.8mW Power Consumption

Capable of Achieving Even Lower Power Consumption with support of a 1-bit PDM signal

Key Features

  • Maximum Sampling Frequency/Resolution :  192kHz/32-bit
  • S/N (SNR) :  109dB
  • Distortion (THD+N) :  -101dB
  • Sound Color Digital Filter :  4 types
  • Power consumptoin :  2.8mW (fs=48kHz)
