Description

The AK4556VT is an interface-CODEC electronic component model that belongs to the AK4556 series. The model has a low voltage of 24-bit and 192kHz CODEC suitable for high-performance digital audio subsystems powered by a battery. The AK4556VT boasts high dynamic performance to power supply voltage ratios with 103dB and 106dB SNR for ADC and DAC, respectively, and supports sampling rates up to 216kHz. Additionally, the AK4556VT reduces jitter sensitivity by employing an integrated switched-capacitor filter, resulting in minimized pin counts and external filtering requirements. The AK4556VT's small 20-pin TSSOP packaging makes it an ideal choice for space-sensitive applications.
