AK4376AECB 32-bit digital-to-analog converter 384k I²S 36-CSP
The AK4376AECB is a low-power, advanced 32-bit stereo digital-to-analog converter (DAC) with an integrated headphone amplifier from Asahi Kasei Microsystems (AKM), housed in a compact 36-pin CSP package with 0.4 mm pitch. It supports a wide range of sampling rates from 8 kHz to 192 kHz and operates from multiple supply rails: 1.7–1.9 V for analog, core, and headphone/charge pump domains, and 1.65–3.6 V for the digital I/O interface. The device integrates a high-performance DAC, digital filters with selectable roll-off characteristics, and a stereo headphone driver, making it ideal for space-constrained and battery-powered audio applications.
Key features include a 32-bit stereo DAC with advanced digital filtering, supporting both slow and sharp roll-off filter modes for flexible sound tuning. The integrated headphone amplifier delivers high-quality audio output with low distortion and noise, while the on-chip charge pump and LDOs provide efficient power management. The device supports master and slave audio interface modes with I2S-compatible serial audio input (BCLK, LRCK, SDATA) and I2C control interface for register configuration. It also includes a crystal oscillator interface (XTI/XTO) and external master clock input (MCKI), along with comprehensive power-down and power management registers to minimize power consumption in portable applications.
Alternative audio DAC Models
● AK4376A: The base version of the 32-bit DAC with headphone amplifier, offering identical performance and features in the same 36-pin CSP package.
● AK4366: A low-power 24-bit 2-channel DAC with headphone amplifier, providing a cost-effective solution for applications that can accept 24-bit resolution instead of 32-bit.
● AK4331: A low-power advanced 32-bit DAC with headphone amplifier and sample rate conversion, offering enhanced digital processing features for audio systems requiring flexible sample rate handling.
