AK7601VQ

Overview

The AK7601VQ is a high-feature digital audio processor integrating an audio CODEC with three stereo ADCs and six stereo DACs, housed in a 48-pin LQFP package. It operates on a single 5.0V supply and includes delay line memory for signal processing. The analog inputs support quasi-differential or single-ended configurations with a 4:1 stereo selector feeding two-channel 97dB ADCs, plus a monaural ADC for guidance sound. Digital inputs feature a 3:1 selector with asynchronous Sample Rate Converter (SRC) compatibility for sources like DVD and Blu-ray. The six-channel DAC provides full-range digital volume control and achieves 102dB dynamic range with single-ended outputs.

Feature Summary

• Integrates 3-channel ADC and 6-channel DAC with delay line memory
• Includes asynchronous Sample Rate Converter (SRC) for digital input selection
• Supports quasi-differential/single-ended analog inputs with 4:1 stereo selector
• Operates on a single 5.0V power supply

Applications

• Digital audio systems requiring SRC functionality
• DVD and Blu-ray player audio processing
• Digital broadcasting equipment
• Car audio systems with guidance sound requirements

Part Context

The AK7601VQ belongs to the AK7601 series of digital audio processors from Asahi Kasei Microdevices. It is functionally related to the AK7601A, which shares similar specifications including the 3-ADC/6-DAC architecture and SRC capabilities. The VQ suffix typically denotes the specific tape and reel packaging variant for this component family.

Replacement Considerations

The AK7601A is a closely related part within the same product family, sharing identical core functional specifications such as the 3-channel ADC, 6-channel DAC configuration, and asynchronous SRC integration. Designers should verify pinout compatibility and packaging differences between the VQ and A variants before substitution.
