AK4359AVF

Digital To Analog Converters Overview

The AK4359AVF is an eight-channel, 24-bit digital-to-analog converter (DAC) from Asahi Kasei Microdevices. It utilizes a multi-bit architecture to deliver high dynamic range and linearity, achieving a signal-to-noise ratio of 106dB and THD+N of -94dB. The device supports sampling rates from 8kHz to 192kHz and features a single-ended SCF output with a second-order analog low-pass filter. It accepts PCM data formats including I2S and TDM, operating on a 4.5V to 5.5V supply within a 30-pin VSOP package.

Digital To Analog Converters Feature Summary
