AK4382AVT

ADCs/DACs - Special Purpose Overview

The AK4382AVT is a 24-bit audio digital-to-analog converter (DAC) manufactured by Asahi Kasei Microdevices. It supports sampling rates from 8 kHz to 192 kHz and utilizes an 8-times FIR digital filter with multi-bit architecture for improved linearity and THD+N performance. The device features on-chip switched capacitor filters (SCF), eliminating the need for external AC coupling capacitors. It operates on a single 5V supply and communicates via I2S or MSB/LSB justified interfaces. The component is housed in a compact 16-pin TSSOP package, designed for high tolerance to clock jitter.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 192 kHz maximum sampling rate
• Integrated SCF outputs remove requirement for external AC coupling capacitors
• THD+N of -94 dB and dynamic range of 112 dB
• Supports I2S, 24-bit MSB justified, and 20/16-bit LSB justified data formats

ADCs/DACs - Special Purpose Applications

• DVD Audio systems
• Home theater amplifiers
• Car audio navigation units
• Digital music players

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'VT' against the manufacturer datasheet to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with 5V logic levels and analog supply requirements during sourcing. Check for RoHS compliance status as per current manufacturing revisions.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a cost-effective solution with integrated filtering is required. It is suitable for applications where board space is limited due to the small 16-pin TSSOP footprint. Consider the 5V power supply constraint compared to lower voltage alternatives.

ADCs/DACs - Special Purpose Part Context

The AK4382 series belongs to AKM's mid-range audio DAC portfolio, balancing performance and cost. The AVT variant specifically denotes the surface-mount TSSOP package configuration within the AK4382 family, distinct from other package options like the standard TSSOP without the specific suffix designation found in broader listings.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements are not explicitly listed in public documentation. Evaluate the AK4384ET for higher channel counts or the AK4381 for stereo configurations, noting differences in resolution and package size.
