Digital To Analog Converters datasheet and documents for AK4381VT

AK4381VT

Digital To Analog Converters Overview

The AK4381VT is a 2-channel, 24-bit stereo digital-to-analog converter (DAC) from Asahi Kasei Microsystems. It utilizes a multi-bit delta-sigma architecture to achieve a dynamic range of 108dB and THD+N of -94dB at 44.1kHz. The device supports sampling rates up to 192kHz with internal oversampling ratios of 128x, 64x, or 32x depending on the mode. It features full differential switched-capacitor filter (SCF) outputs, eliminating the need for external AC coupling capacitors. Powered by a single 5V supply (4.75V to 5.25V), it operates within an ambient temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

24-bit resolution with 108dB dynamic range and -94dB THD+N performance
Full differential SCF outputs remove the requirement for AC coupling capacitors
Supports sampling rates from 8kHz to 192kHz with selectable oversampling modes
Integrated digital de-emphasis for 32kHz, 44.1kHz, and 48kHz audio formats

Digital To Analog Converters Applications

DVD-Audio systems
High-fidelity audio equipment
Professional audio interfaces

Digital To Analog Converters Procurement Notes

Verify that the component marking matches 'AKM 4381VT' and includes the lot/date code format XXYYY. Confirm the package is a 16-pin TSSOP with a 0.65mm pitch. Ensure the supplier provides documentation confirming the part meets the specified operating voltage of 4.75V to 5.25V and the temperature range of -40°C to +85°C.

Digital To Analog Converters Selection Notes

Select this component when a high-performance stereo DAC with integrated filtering is required. It is pin-compatible with the AK4382A, allowing for potential design upgrades. Consider the 16-pin TSSOP package dimensions (6.4mm x 5.0mm) for space-constrained layouts. Verify system clock requirements against the supported MCLK frequencies for the desired sampling speed mode.

Digital To Analog Converters Part Context

The AK4381VT is part of the AK438x series of 24-bit stereo DACs. It serves as a cost-effective solution for audio systems requiring wide dynamic range and linearity. The 'VT' suffix indicates the specific tape-and-reel packaging variant in the 16-pin TSSOP form factor.
