AK5367EF

ADCs/DACs - Special Purpose Overview

The AK5367EF 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. Operating with sampling rates from 32kHz to 96kHz, it supports I2S and MSB justified audio interfaces. The component requires a 4.5V to 5.5V analog supply and a 3.0V to 3.6V digital supply, housed in a 30-pin VSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix EF against the manufacturer datasheet to confirm pinout and electrical characteristics match the design requirements. Check current availability status as components may be subject to discontinuation or lifecycle changes. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and revision levels prior to integration.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 24-bit ADC with integrated input switching and PGA is required for compact audio designs. Confirm that the system can accommodate the separate analog (4.5-5.5V) and digital (3.0-3.6V) power supplies. Verify that the 30-pin VSOP package fits the PCB layout constraints and that the 96kHz maximum sampling rate meets the application bandwidth needs.

ADCs/DACs - Special Purpose Part Context

The AK5367EF belongs to the AK5367 series of audio ADCs from Asahi Kasei Microdevices. This series focuses on high-integration solutions for portable and stationary audio recording. The EF suffix typically denotes the specific tape-and-reel packaging variant within the standard 30-pin VSOP form factor used across the family.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements are limited due to the specific combination of 4-channel input selection and dual-supply operation. Evaluate other AKM ADCs such as the AK5367AEF for identical specifications or higher-resolution alternatives like the AK5388 if multi-channel capability beyond stereo is needed.
