AD1856RZ

Overview

The AD1856RZ is a single-channel, 16-bit audio digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It utilizes sigma-delta modulation architecture and features a serial interface for data input. The device operates within a temperature range of -25°C to +70°C and consumes 10 mA of working power with a maximum power dissipation of 150 mW. Housed in a 16-lead SOIC package, it provides one analog output channel designed for high-fidelity audio signal reconstruction.
