Overview
The AD1854JRSZRL is a high-performance, single-chip stereo audio Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is designed to deliver exceptional audio quality with a dynamic range of 113 dB and a signal-to-noise ratio (SNR) of 112 dB (A-weighted) at a 48 kHz sample rate. It features a multibit sigma-delta modulator with 'Perfect Differential Linearity Restoration' to reduce idle tones and noise floor, making it ideal for various audio applications.
