AK5358BET

ADCs/DACs - Special Purpose Overview

The AK5358BET is a stereo analog-to-digital converter (ADC) manufactured by Asahi Kasei Microdevices. It features a 24-bit resolution and supports sampling rates from 8kHz to 96kHz, utilizing Enhanced dual bit delta-sigma modulation techniques. The device operates with separate analog (4.5V to 5.5V) and digital (2.7V to 3.6V) power supplies. It integrates linear phase digital anti-alias filtering and a digital high-pass filter for DC-offset cancellation. The component provides a signal-to-noise ratio of 102dB and dynamic range of 102dB, housed in a compact 16-pin TSSOP package suitable for surface mount installation.

ADCs/DACs - Special Purpose Procurement Notes

Verify the current manufacturing status as the AK5358 series has been subject to end-of-life notifications. Confirm availability through authorized distributors or check for pin-compatible alternatives such as the AK5357, AK5359, or AK5381 if direct procurement is unavailable. Ensure compliance with RoHS3 specifications during sourcing.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring low-cost, high-accuracy stereo audio digitization without external analog components due to single-ended inputs. Verify that the system clock requirements align with the supported master clock frequencies (256fs/384fs/512fs/768fs). Ensure the design accommodates the specific voltage levels for analog and digital domains.

ADCs/DACs - Special Purpose Part Context

The AK5358BET belongs to the AK5358 family of stereo ADCs designed for consumer and professional audio systems. It is part of a broader lineup that includes pin-compatible variants like the AK5357, AK5359, and AK5381, allowing for flexible design integration within AKM's audio conversion portfolio.

ADCs/DACs - Special Purpose Replacement Considerations

Pin-compatible substitutes include the AK5357, AK5359, and AK5381. These alternatives maintain the same package footprint and interface compatibility, facilitating direct replacement in existing designs where the original part is discontinued.
