AK4127VF

Overview

The AK4127VF is a two-channel digital sample rate converter manufactured by Asahi Kasei Microdevices. It operates within a supply voltage range of 3V to 3.6V and supports sampling rates from 8kHz to 216kHz. The device utilizes an I2S interface for data transmission and is housed in a 30-VSOP (30-LSSOP) surface-mount package with a width of 5.60mm. It is designed for digital audio interfacing applications and functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Two-channel digital sample rate conversion capability
• Supports sampling frequencies between 8kHz and 216kHz
• I2S digital audio interface compatibility
• Operates on a single 3V to 3.6V power supply

Applications

• Digital audio interfacing systems
• Audio equipment requiring sample rate conversion
• Professional audio signal processing

Procurement Notes

Verify component status as the AK4127VF is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market suppliers. Ensure the 30-VSOP package matches the target PCB footprint. Check RoHS compliance status for environmental regulations. Validate that the I2S interface requirements align with the system design before procurement.

Selection Notes

Select this component when a two-channel sample rate converter is required for digital audio paths. Ensure the input clock and data formats are compatible with the I2S interface. Verify that the 3V to 3.6V supply voltage fits the system power architecture. Consider the 30-VSOP package dimensions for board space constraints. Confirm thermal performance meets the -40°C to 85°C operating range requirements.

Part Context

The AK4127VF belongs to the AK4127 series of audio integrated circuits. It serves as a specialized solution for converting digital audio signals between different sampling rates. The device integrates necessary logic for handling I2S data streams. It is part of Asahi Kasei Microdevices' portfolio of audio processing components.

Replacement Considerations

As the AK4127VF is marked as obsolete, direct replacements may be limited. Evaluate other AKM sample rate converters for pin compatibility and functional equivalence. Verify that alternative components support the same 30-VSOP package or require PCB redesign. Check if newer models offer improved sampling rate ranges or lower power consumption.
