AK4346EF

Digital To Analog Converters Overview

The AK4346EF is a 6-channel, 24-bit stereo digital-to-analog converter (DAC) from Asahi Kasei Microdevices. It operates on a single +3.3V supply with a voltage range of 2.7V to 3.6V. The device supports sampling rates from 8kHz to 192kHz and utilizes an advanced multi-bit Delta-Sigma architecture. Key electrical specifications include a dynamic range and signal-to-noise ratio of 104dB, and a total harmonic distortion plus noise (THD+N) of -90dB. It features integrated switched-capacitor filters and second-order analog low-pass filters, reducing the need for external components.

Digital To Analog Converters Feature Summary

• Six-channel output capability supporting up to 192kHz sampling rates
• Integrated channel-independent digital attenuator with 256 linear steps
• Supports both 3-wire serial and I2C control interfaces
• Includes zero detect function and soft mute operation

Digital To Analog Converters Applications

• Multi-channel audio systems requiring independent channel control
• Home theater receivers and AV processors
• Professional audio mixing consoles
• Digital TV and set-top box audio processing

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'EF' corresponds to the -20°C to +85°C operating temperature range. Confirm the package type is 30-pin VSOP. Ensure the design accounts for the requirement that all input pins except P/S and TDM0 must not be left floating during operation.

Digital To Analog Converters Selection Notes

Select the AK4346VF variant if the application requires an extended industrial temperature range of -40°C to +85°C. Consider the AKD4346 evaluation board for initial system testing and verification of clocking and interface timing requirements before final production integration.

Digital To Analog Converters Part Context

The AK4346 belongs to the AK434x series of high-performance DACs. It is designed to replace older discrete solutions by integrating digital filtering, volume control, and analog output buffers into a single component. This integration helps reduce board space and minimizes external component count in complex multi-channel audio designs.

Digital To Analog Converters Replacement Considerations

The AK4346VF serves as the direct temperature-range alternative to the EF variant. No other cross-model substitutes are confirmed in the provided documentation.
