Overview
The AK4702VQ is a stereo digital-to-analog converter integrated with an AV SCART switch, manufactured by Asahi Kasei Microdevices. Designed for digital set-top box systems, it features two-channel DAC functionality alongside analog switching capabilities for audio and video signals. The device operates on a single 5V power supply and utilizes a compact 48-pin LQFP package to minimize board space. It supports differential or single-ended inputs and provides stereo outputs compatible with TV and VCR SCART interfaces.
Feature Summary
- Integrates 2-channel DAC with AV SCART switching for unified audio/video processing
- Includes pop noise-free circuitry for stable power-on and power-off transitions
- Supports multiple video input configurations including CVBS, Y, R/C, G, and B signals
- Features low power dissipation with dedicated standby mode for energy efficiency
Applications
- Digital set-top box systems
- AV receivers with SCART connectivity
- Home theater PC (HTPC) audio/video output stages
- Multimedia players requiring integrated DAC and signal routing
Procurement Notes
Verify the specific suffix 'VQ' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Check for obsolescence notices as AKM frequently updates component lifecycles. Ensure the supplier provides original manufacturer documentation rather than generic descriptions to validate authenticity and revision history.
Selection Notes
Select this component when a combined DAC and SCART switch solution is required to reduce bill of materials count. It is suitable for designs needing ground-referenced outputs without external coupling capacitors in the video path. Consider thermal performance within the LQFP package if operating near maximum temperature limits. Verify that the 5V supply constraint aligns with the system power architecture.
Part Context
The AK4702VQ belongs to the AK470x series of A/V switches and DACs from Asahi Kasei Microsystems. This family targets consumer electronics requiring high-quality audio conversion and video signal routing in a single package. It serves as a bridge between digital source components and analog display or playback devices via standard SCART connectors.
Replacement Considerations
The AK4702EQ is a pin-compatible alternative within the same product family. Verify electrical specifications and package tolerance differences before substitution. Other series members like AK4703 or AK4707 offer similar switching functions but may lack the integrated DAC capability.
