AK4556VT规格书详情
GENERAL DESCRIPTION
The AK4556 is a low voltage 24bit 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 AK4556
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.
FEATURES
