AK5367AEF

ADCs/DACs - Special Purpose Overview

The AK5367AEF is a high-performance 24-bit stereo analog-to-digital converter (ADC) designed for consumer audio and digital recording applications. It utilizes an Enhanced Dual-Bit modulator architecture to achieve a dynamic range of 102dB. The device integrates a 4-channel stereo input selector, a programmable gain amplifier, and a digital high-pass filter for offset cancellation. It supports sampling rates from 32kHz to 96kHz and operates with an analog supply voltage of 4.5V to 5.5V and a digital supply of 3.0V to 3.6V. The component is housed in a 30-pin VSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'AEF' against the manufacturer's current product status, as legacy AKM components may have undergone obsolescence notices or packaging changes. Confirm RoHS compliance and moisture sensitivity level requirements prior to procurement. Ensure the analog supply voltage range matches the system design constraints.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 24-bit ADC with integrated input switching and low-offset characteristics is required for compact audio designs. The internal charge pump simplifies power management by removing output coupling capacitors. Verify that the 30-pin VSOP package fits the PCB layout and that the 4.5V–5.5V analog supply is available in the target application.

ADCs/DACs - Special Purpose Part Context

The AK5367AEF belongs to the AK5367 series of stereo ADCs from Asahi Kasei Microdevices. It is part of a family of high-integration audio converters designed to reduce external component counts in digital audio workflows. The 'EF' suffix typically denotes the specific tape-and-reel packaging configuration for surface-mount assembly.
