AK4519 Datasheet Low Power 20-bit Adc/dac

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: ASAHI KASEI [AK4519] AK4519 Low Power 20 bit ∆Σ ADC&DAC with.

General Description

AK4519 is low voltage 20bit A/D & D/A converter for portable digital audio system.

In the AK4519, 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 AK4519 are single-ended, therefore, external filter is not required.
