概述

Description

AK4430ET is a stereo digital-to-analog converter (DAC) IC from Asahi Kasei Microdevices (AKM). It converts 24-bit digital audio to analog for high-fidelity playback and is used in audio gear such as DAC boards, CD/DVD players, and receivers. Typical features include:
- 24-bit resolution, up to high sampling rates (often 192 kHz)
- Support for multiple digital input formats (I2S, left-justified, DSP)
- Low distortion and high SNR
- Analog outputs that usually require external I/V conversion and reconstruction filtering
For exact specs, interfaces, and pinout, please consult the official AK4430ET datasheet.

Features

Here are the common features of AK4430ET (AKM AK4430 family) DACs:
- 24-bit stereo DAC
- Up to 192 kHz sampling rate
- Differential current-output DAC (requires external I/V stage)
- Digital input formats: I2S (and often compatible left-justified/right-justified)
- Internal digital filter with selectable roll-off
- Digital de-emphasis support
- Soft mute and power-down control
- High dynamic range with low distortion (low THD+N)
- Low jitter tolerance and robust clocking
- Suitable for line-out/headphone or AV applications
Note: Exact specs can vary by revision; refer to the AK4430ET datasheet for precise voltage, interface, and package details.

Package

AK4430ET uses an 8-pin small-outline package (SOP-8 / MSOP-8).

Pinout

- Pin count: 28 pins (package options include SSOP-28 / QFP-28)
- Primary function: 24-bit stereo digital-to-analog converter (DAC). It has I2S-compatible digital input (bit clock, word select, data), converts to analog left and right outputs (LOUT/ROUT), requires separate analog and digital power, and includes control pins (e.g., MUTE/PDN) and ground/reference pins. For exact pin mapping, refer to the AK4430ET datasheet.

Manufacturer

The AK4430ET is manufactured by Asahi Kasei Microdevices Corporation (AKM). AKM is a Japanese semiconductor company (a subsidiary of Asahi Kasei) that designs and manufactures analog, mixed-signal, and digital ICs, with a focus on audio DACs/ADCs and related ICs for consumer and professional electronics.

Application

- High‑fidelity consumer audio equipment (Hi‑Fi receivers, DAC modules)
- AV gear (CD/DVD/Blu‑ray players, set‑top boxes)
- USB/HD digital audio interfaces and external DACs
- Professional audio gear (digital mixers, studio monitors)
- Automotive infotainment and car audio systems

Equivalent

AK4430ET is a 24-bit stereo DAC (I2S) from AKM, typically up to ~192 kHz. Close equivalents (not pin‑compatible) from other vendors include:
- Cirrus Logic CS4398
- TI PCM5242 / PCM1794A
- Analog Devices AD1955
- Wolfson WM8740 / WM8741
- ESS ES9038Q2M
Note: check pinout, interface, and performance specs when substituting.
