Description

The AK4556VT is a low voltage 24-bit 192kHz CODEC for high performance battery powered digital audio subsystems. The dynamic performance to power supply voltage ratio is very high, attaining 103dB and 106dB SNR for ADC and DAC, respectively. Sampling rates up to 216kHz are supported. 
The AK4556VT reduces jitter sensitivity by using an integrated switched-capacitor filter. The analog inputs and outputs are single-ended to minimize pin count and external filtering requirements. Packaged in a very small 20-pin TSSOP, the AK4556 is ideal for space-sensitive applications.

Key Features

  • Single-ended ADC | Equipped with HPF for DC-offset cancellation, Dynamic Range S / N = 103dB @VA = 3.0V
  • Single-ended DAC | Equipped with digital de-emphasis filter, Dynamic Range S / N = 106dB @VA = 3.0V

Applications

  •                                 Digital audio equipment, etc.
