AK5365VQ

The AK5365VQ from Asahi Kasei Microdevices is a high-performance 24-bit, 96kHz sampling Analog-to-Digital Converter (ADC) designed for consumer audio and digital recording applications. Leveraging AKM’s Enhanced Dual-Bit modulator architecture, this ADC achieves an impressive dynamic range of 103dB with a high level of integration.

Key features include a 5-channel stereo input selector, an input Programmable Gain Amplifier (PGA) with adjustable gain from +12dB to 0dB in 0.5dB steps, and an Auto Level Control (ALC) function. It also incorporates a digital High-Pass Filter (HPF) for offset cancellation and a digital attenuator. The audio interface format is 24-bit MSB justified, I2S compatible.

This device operates within a temperature range of -40°C to 85°C and is available in a 44-pin LQFP package. It supports both 3-wire serial µP Interface and I2C-Bus communication, and can operate in Master or Slave mode. The power supply requirements are AVDD: 4.75V to 5.25V and DVDD: 3.0V to 5.25V.

The AK5365VQ is well-suited for applications such as CD and DVD recording systems, digital audio processors, and other consumer audio equipment requiring high-fidelity analog-to-digital conversion.
