AK4556 - 3V 192kHz 24-Bit CODEC

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.

Features

  • † Single-ended ADC - Dynamic Range, S/N: 103dB@VA=3.0V - S/(N+D): 91dB@VA=3.0V - HPF for DC-offset cancel (fc = 1Hz @ fs=48kHz) - HPF can be disabled † Single-ended DAC - Dynamic Range, S/N: 106dB@VA=3.0V - S/(N+D): 90dB@VA=3.0V - Digital de-emphasis for 32kHz, 44.1kHz and 48kHz sampling † Audio I/F format: MSB First, 2’s Complement - ADC: 24bit MSB justified or I2S compatible - DAC: 24bit MSB justified, 24bit LSB justified or I2S compatible † Input/Output Voltage: ADC = 2.1Vpp @ VA=3.0V DAC = 2.

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 † Single-ended ADC - Dynamic Range, S/N: 103dB@VA=3.0V - S/(N+D): 91dB@VA=3.
