AD1858JRS

Overview

The AD1858JRS is a stereo, single-supply 16-bit sigma-delta digital-to-analog converter (DAC) from Analog Devices. It integrates a 128x oversampling interpolation filter, a multibit sigma-delta modulator with dither, and analog output drive circuitry. The device accepts serial audio data in 16-bit right-justified or DSP serial port compatible modes. Operating on a single +5 V supply, it delivers 94 dB dynamic range and -90 dB THD+N performance. Key features include digital de-emphasis for Redbook CD playback, mute functionality, and power-down mode. It is housed in a 20-lead SSOP package and operates within a temperature range of 0 °C to +70 °C.

Feature Summary

16-bit resolution with 94 dB dynamic range and -90 dB THD+N
128x oversampling interpolation filter with multibit sigma-delta modulator
Supports right-justified and DSP serial port input modes
Integrated digital de-emphasis and zero-crossing mute

Applications

CD, CD-R, DAT, DCC and MD players
Digital Cable TV and Direct Broadcast Satellite Set-Top Decoder Boxes
Video Laser Disk, Video CD and CD-I Players

Procurement Notes

Verify the specific ordering suffix JRS corresponds to the 20-lead SSOP package and 0 °C to +70 °C operating temperature range. Confirm interface compatibility with the host processor's serial clock requirements before integration. Check current availability status as component lifecycles may change.

Selection Notes

Select the AD1858JRS when a 16-bit stereo DAC with integrated reconstruction filtering is required. Ensure the system master clock can be provided at 256 or 384 times the sample frequency. Verify that the serial interface timing meets the setup and hold requirements for BCLK and LRCLK signals.

Part Context

The AD1858JRS is part of the AD1857/AD1858 family of stereo sigma-delta DACs. While the AD1857 supports 18-bit and 20-bit resolutions with I2S and left-justified modes, the AD1858 is optimized for 16-bit applications with right-justified and DSP modes. Both share identical analog performance characteristics and internal architecture.
