AK4621EF
Overview
The AK4621EF is a high-performance 24-bit stereo audio codec featuring a single-ended ADC and DAC capable of sampling rates up to 192kHz. It is designed for high-end audio applications, offering a wide dynamic range of 115dB for both input and output stages while operating on dual 5V analog and 3.3V digital power supplies.
Why Choose This Part
The AK4621EF stands out with its symmetrical 115dB dynamic range for both ADC and DAC, ensuring consistent signal integrity across the entire signal chain. It simplifies system design with integrated features like a digital high-pass filter for offset cancellation, an output digital attenuator, and a high-tolerance clock circuit that resists jitter-induced distortion.
Applications
Key Specifications
Getting Started
Integration requires a dual-voltage power supply design (5V AVDD and 3.3V DVDD) and a stable master clock. Engineers should interface the device via the I2S/Serial port to a DSP or MCU, ensuring the 30-pin VSOP package is mounted with adequate decoupling capacitors as close to the supply pins as possible to maintain the 102dB S/N ratio.
