Overview

ASAHI KASEI [AK4551] AK4551 Low Power & Small Package 20bit ∆Σ CODEC GENERAL DESCRIPTION The AK4551 is a low voltage 20bit A/D & D/A converter for portable digital audio system.
In the AK4551, the loss of accuracy form clock jitter is also improved by using SCF techniques for on-chip post filter.
Analog signal input/output of the AK4551 are single-ended, therefore, any external filters are not required.
The AK4551 is suitable for portable digital audio system, as the AK4551 is lower power dissipation and a smaller package than AK4519.
FEATURES o HPF for DC-offset cancel (fc=3.
4Hz) o Single-ended ADC - S/(N+D): 82dB@VDD=2.
5V - Dynamic Range, S/N: 89dB@VDD=2.
5V o Single-ended DAC - Digital ...
