Digital To Analog Converters datasheet and documents for AK4344ET
Digital To Analog Converters Overview
The AK4344ET is a 24-bit stereo digital-to-analog converter (DAC) utilizing an Advanced Multi-Bit ΔΣ architecture. It operates on a single power supply ranging from 2.7V to 3.6V, typically 3.3V. The device achieves a dynamic range and signal-to-noise ratio of 100dB with a THD+N of -90dB at 0dBFS. It supports sampling rates from 8kHz to 96kHz and integrates an 8x FIR digital filter alongside switched-capacitor and continuous-time filters for jitter tolerance. The analog output voltage level can be set up to 1Vrms, centered around VCOM.
Digital To Analog Converters Feature Summary
- 24-bit resolution with 100dB Dynamic Range/SNR and -90dB THD+N
- Sampling rates from 8kHz to 96kHz with 8x FIR Digital Filter
- Integrated SCF and CTF filters for high clock jitter tolerance
- Single-ended output buffer with selectable voltage levels (up to 1Vrms)
- Supports 4-wire and 3-wire µP control interfaces
Digital To Analog Converters Applications
- Portable audio systems
- Home audio equipment
- Digital audio players
- Embedded audio interfaces
Digital To Analog Converters Procurement Notes
Verify the package marking code 'AKM 4344ET' against the datasheet revision MS0641-E-01. Confirm the pin configuration matches the 16-pin TSSOP layout with 0.65mm pitch. Ensure that TEST1 is connected to VSS and TEST2 is left open during implementation. Check that all digital input pins are terminated properly to avoid floating states.
Digital To Analog Converters Selection Notes
Select this component when a low-voltage, low-power stereo DAC is required for portable or battery-operated devices. It is suitable for applications needing high jitter immunity due to the integrated SCF/CTF filters. Choose between 4-wire or 3-wire interface modes based on microcontroller pin availability. Ensure the system supports the required master clock frequencies relative to the sampling rate.
Digital To Analog Converters Part Context
The AK4344ET is part of Asahi Kasei Microdevices' (AKM) line of 24-bit audio DACs. It is designed for space-constrained applications using a 16-pin TSSOP package. The device replaces older generations by offering improved dynamic range and lower power consumption while maintaining compatibility with standard audio interfaces like I2S.
Digital To Analog Converters Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult AKM directly for current equivalent products or updated series replacements.
