AK4490EQ Description

Short technical summary and product information.

The AK4490EQ is a premium 32-bit 2-channel audio digital-to-analog converter (DAC) from Asahi Kasei Microdevices (AKM). It is designed for high-resolution audio applications, supporting PCM data rates up to 768kHz and DSD data rates up to 11.2MHz.

 

The DAC achieves a typical THD+N of -112 dB and a signal-to-noise ratio (SNR) of 120 dB, with a dynamic range of 120 dB (123 dB in mono mode). It integrates five types of 32-bit digital filters: Short Delay Sharp Roll-off, Short Delay Slow Roll-off, Sharp Roll-off, Slow Roll-off, and Super Slow Roll-off, allowing flexible sound tuning. The device accepts data interfaces including I²S and DSD.

 

The AK4490EQ operates with dual supply voltages: analog and digital core (DVDD/AVDD) from 3.0V to 3.6V, and a separate supply (VDD1/2) from 4.75V to 7.2V. It is available in a 48-LQFP (7x7mm) surface mount package, with an operating temperature range of -40°C to 85°C.

 

Typical applications include AV receivers, CD/SACD players, network audio, USB DACs, car audio systems, and professional audio equipment. The device is RoHS3 compliant (unverified) and has an MSL of 1.
