AK4346VF

Digital To Analog Converters Overview

The AK4346VF is a 6-channel, 24-bit digital-to-analog converter (DAC) from Asahi Kasei Microdevices. It operates on a single +3.3V power supply with a range of 2.7V to 3.6V and supports sampling rates from 8kHz to 192kHz. The device utilizes an advanced multi-bit architecture for the modulator to achieve a dynamic range and signal-to-noise ratio of 104dB, along with a THD+N of -90dB. It features a switched-capacitor filter and a second-order analog low-pass filter in the output circuit, reducing external filtering requirements. The VF suffix indicates an extended operating temperature range of -40°C to 85°C.

Digital To Analog Converters Feature Summary

• Six-channel 24-bit DAC with 104dB Dynamic Range/S/N and -90dB THD+N
• Sampling rates from 8kHz to 192kHz with high tolerance to clock jitter
• Integrated channel-independent digital attenuator with 256 linear steps
• Supports 3-wire serial and I2C control interfaces with multiple audio data formats

Digital To Analog Converters Applications

• Multi-channel audio systems requiring independent channel control
• Professional audio equipment and digital mixing consoles
• Home theater and surround sound processors
• Digital audio workstations and recording interfaces

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'VF' confirms the -40°C to 85°C industrial temperature grade, distinct from the 'EF' commercial grade. Confirm package type is 30-pin VSOP. Ensure power supply voltages are within the 2.7V to 3.6V specification. Check that the source document matches the MS0531-E-00 revision date of July 2006.

Digital To Analog Converters Selection Notes

Select the AK4346VF when six independent stereo channels are required in a single component. It is suitable for applications needing digital volume control per channel without external amplifiers. Consider the integrated SCF and analog LPF if minimizing external passive components is a priority. Ensure the system supports the required master clock frequencies (up to 1152fs) and interface protocols (I2S, TDM, etc.).

Digital To Analog Converters Part Context

The AK4346 is part of Asahi Kasei's 24-bit DAC portfolio, designed for high-fidelity audio reproduction. The VF variant specifically addresses industrial and automotive environments requiring wider temperature stability compared to the EF version. It complements other AKM audio codecs and converters by providing dedicated multi-channel conversion capabilities.

Digital To Analog Converters Replacement Considerations

The AK4346EF is the commercial temperature grade equivalent with a -20°C to 85°C range. Verify pin compatibility and electrical specifications before substitution. No direct cross-model replacements are documented in the provided datasheet.
