Descripción general

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.
