The AD1856R is a single-channel, 16-bit audio digital-to-analog converter (DAC) manufactured by Analog Devices. It features a serial input interface and operates within a temperature range of -25°C to +70°C. The device consumes 10 mA of operating current with a power dissipation of 150 mW. It is housed in a 16-lead SOIC package and provides one analog output channel. This component is designed for high-fidelity audio applications requiring precise digital conversion.
The AD1856R belongs to the AD1856 series of audio DACs from Analog Devices. It is pin-compatible with related models such as the AD1851 and AD1860, facilitating design flexibility within the same product family while maintaining specific performance characteristics for mono audio signal processing.
The AD1851R is a pin-compatible alternative within the same series. Designers should verify that the settling time and SNR specifications of the substitute meet the original system requirements before implementation.
