AK4614VQ

Codecs Overview

The AK4614VQ is a single-chip audio CODEC manufactured by Asahi Kasei Microdevices/AKM, housed in an 80-pin LQFP package. It integrates six 24-bit ADC channels and twelve 24-bit DAC channels. The device supports sampling frequencies up to 192kHz across Normal, Double, and Quad Speed modes. Analog power supply ranges from 3.0V to 3.6V, while digital supply operates between 1.6V and 2.0V. Typical performance includes ADC S/(N+D) of 97dB (differential) and DAC S/(N+D) of 100dB (differential).

Codecs Feature Summary

• Integrates six-channel ADCs with Enhanced Dual Bit architecture and twelve-channel DACs with Advanced Multi-Bit architecture for low noise.
• Supports both single-ended and differential analog inputs and outputs with individual channel digital volume control.
• Features master/slave operation with flexible serial and I2C bus interfaces for system configuration.
• Includes linear phase digital filters, de-emphasis filters, and zero detect functions for signal processing.

Codecs Applications

• Home theater systems
• Professional audio equipment
• Car audio systems

Codecs Procurement Notes

Verify the specific ordering suffix matches the required temperature range and package variant. Confirm that the analog and digital supply voltages align with the target system design before finalizing orders. Ensure compatibility with existing control interface protocols.

Codecs Selection Notes

Select this component when multi-channel input and output capabilities are required within a single integrated circuit. Consider the 80-pin LQFP footprint for PCB layout constraints. Evaluate power consumption requirements against the specified operating current at the target sampling frequency.

Codecs Part Context

This model belongs to the AK4614 series of high-performance audio CODECs. It is designed for applications requiring multiple independent audio channels. The VQ suffix indicates the industrial temperature grade and specific packaging configuration provided by the manufacturer.

Codecs Replacement Considerations

The datasheet explicitly compares the AK4614 to the AK4628. While functionally similar, they differ significantly in channel count, package size, and power supply requirements. Direct pin-to-pin replacement is not supported due to the different pin counts and voltage specifications.
