AK8826VN

Overview

The AK8826VN is a multi-format video encoder IC manufactured by Asahi Kasei Microdevices. It supports both NTSC and PAL standards for SD video encoding. The device integrates three DAC channels for audio output. It operates with an analog supply voltage range of 2.7V to 3.6V and a digital supply voltage range of 1.65V to 2V. The component is housed in a 48-TFQFN package with exposed pad, measuring 7.2x7.2 mm. It is designed for surface mount installation. The part status is listed as obsolete.

Feature Summary

• Supports HD/SD multi-format video encoding
• Integrates three-channel DAC for audio processing
• Compatible with NTSC and PAL video standards

Applications

• Video encoder systems requiring NTSC/PAL support
• HD/SD multi-format video processing equipment
• Devices integrating video and audio encoding functions

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Check for RoHS3 compliance documentation. Confirm package integrity upon receipt. Validate datasheet revisions against current engineering requirements. Ensure supply chain stability given end-of-life designation.

Selection Notes

Evaluate compatibility with existing system voltage levels, specifically the separate analog and digital supply requirements. Consider the 48-QFN package constraints for PCB layout. Verify that NTSC/PAL encoding meets application needs. Assess thermal management for the exposed pad design. Review obsolescence implications for long-term production planning.

Part Context

The AK8826VN belongs to the AK8826 family of video encoders from Asahi Kasei Microdevices. It shares functional similarities with the AK8825 but offers specific integration for multi-format video encoding. The component is distinct from decoder variants like the AK8858. It represents a specialized solution for combined video and audio signal conversion in legacy or specific industrial applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. The AK8825 is a related model within the same family. Designers should consult official replacement guides or contact the manufacturer directly for validated alternatives.
