概述

Description

AK4128AEQ is a high-performance stereo PCM digital-to-analog converter (DAC) IC from Asahi Kasei Microdevices (AKM). It’s used to convert digital audio data into analog audio signals for consumer and professional gear.
Key points:
- Resolution and sampling: typically 24-bit, up to 192 kHz.
- Architecture: sigma-delta DAC with selectable digital filters.
- Interfaces: digital inputs such as I2S/Left-Justified with master/slave modes.
- Outputs: differential (current) outputs with an external reconstruction filter; suitable for high-fidelity analog stages.
- Package/variant: AEQ suffix denotes specific package/grade; refer to the datasheet for exact pinout and electrical specs.
Common applications include DAC boards, audio interfaces, CD players, AV receivers, and other high-end audio equipment. For precise specs and pinout, consult the official AKM AK4128AEQ datasheet.

Package

AK4128AEQ uses a 32-pin LQFP package (LQFP-32).

Pinout

28-pin package. It is a 24-bit stereo digital-to-analog converter (DAC) with serial digital input (I2S/Left-Justified) and differential current-output analog stage (external I/V resistor network).

Manufacturer

- Manufacturer: Asahi Kasei Microdevices Corporation (AKM).
- What kind of company: A Japanese semiconductor company that designs and manufactures analog and mixed-signal ICs, especially audio DACs/ADCs, CODECs, and clock devices.

Application

Typical applications for AK4128AEQ:
- High‑fidelity audio equipment (A/D conversion)
- Professional audio gear (audio interfaces, multi‑channel recorders, digital mixers)
- Consumer digital audio devices (CD/DVD/Blu‑ray players, AV receivers, sound bars)
- Automotive infotainment and car audio
- Telecommunication and voice‑processing systems needing high‑quality ADC/DSP functions
