AK5534VN

ADCs/DACs - Special Purpose Overview

The AK5534VN is a 4-channel, 32-bit delta-sigma analog-to-digital converter (ADC) from Asahi Kasei Microdevices. It supports sampling rates up to 768 kHz and achieves a dynamic range of 111 dB, with channel summation modes improving performance to 114 dB (4-to-2) and 117 dB (4-to-1). The device features full differential inputs, selectable digital filters, and DSD output capability up to 11.2 MHz. It operates on a 3.0–3.6 V analog supply and a 1.7–1.98 V or 3.0–3.6 V digital supply, housed in a 48-pin QFN package.

ADCs/DACs - Special Purpose Feature Summary

• 4-channel differential input with 32-bit resolution and 768 kHz maximum sampling rate
• Dynamic range of 111 dB, extendable to 117 dB via channel summation modes
• Integrated selectable digital filters including sharp/slow roll-off LPF and HPF
• Supports PCM (I2S/TDM/MSB justified) and DSD Native formats up to 11.2 MHz

ADCs/DACs - Special Purpose Applications

• Professional audio mixers
• Multi-channel digital recorders
• Digital signal processor (DSP) front-end interfaces

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'VN' corresponds to the 48-pin QFN package and tape & reel orientation as defined in the manufacturer's ordering guide. Confirm that the analog power supply (AVDD) and digital interface supply (TVDD) levels match the required LDO enable configuration for the target application voltage.

ADCs/DACs - Special Purpose Selection Notes

Select this component when four independent differential channels are required within a single IC. Ensure the system design accommodates the separate analog (3.0–3.6 V) and digital (1.7–1.98 V or 3.0–3.6 V) power domains. Consider the channel summation feature if higher dynamic range is needed at the cost of channel count.

ADCs/DACs - Special Purpose Part Context

The AK5534VN belongs to the AK553x series of high-performance audio ADCs. It shares architectural similarities with other members like the AK5534 and AK5554 but is distinct in its fixed 4-channel configuration. The 'VN' suffix typically denotes the specific package type and shipping format for this model line.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include the AK5554VN. For applications requiring different channel counts, consider the 2-channel AK5532 or 6-channel AK5536, though pinouts and register maps may require adaptation.
