Overview
The AD1858JRSRL is a stereo, single-supply 16-bit sigma-delta digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates from a +5 V supply and is housed in a 20-lead SSOP package for temperatures ranging from 0 °C to +70 °C. The device integrates a 128x interpolation filter, a multibit sigma-delta modulator with dither, analog reconstruction filters, and output buffers. It supports continuously variable sample rates and features serial data interfaces compatible with I2S, left-justified, right-justified, and DSP modes. Key performance metrics include a dynamic range of 94 dB (A-weighted) and THD+N of –90 dB.
Feature Summary
- 16-bit resolution with 94 dB dynamic range and –90 dB THD+N performance
- Integrated 128x oversampling interpolation filter and multibit sigma-delta modulator
- Flexible serial input supporting I2S, left-justified, right-justified, and DSP modes
- On-chip voltage reference and analog output buffers driving 2 kΩ loads
Applications
- Digital Cable TV and Direct Broadcast Satellite Set-Top Decoder Boxes
- Video Laser Disk, Video CD and CD-I Players
- CD, CD-R, DAT, DCC and MD Players
- High Definition Televisions and Digital Audio Broadcast Receivers
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm reel specifications and packaging details. Ensure that the component meets all relevant environmental compliance standards required for the intended deployment environment before integration into production systems.
Selection Notes
Select the AD1858JRSRL when a 16-bit stereo DAC with integrated filtering is required. It is suitable for applications needing glueless interconnection to DSPs or AES/EBU receivers. Consider the AD1857 variant if higher resolution (18-bit) or different serial port configurations are necessary for the system design.
Part Context
This component belongs to the AD1857/AD1858 family of stereo sigma-delta DACs. The AD1858 specifically provides 16-bit resolution, whereas the AD1857 offers 18-bit resolution. Both share identical architectures, including the multibit modulator and analog filters, differing primarily in word width and supported serial interface modes.
Replacement Considerations
The AD1857 serves as a higher-resolution alternative within the same package and pinout. Verify compatibility with existing serial clocking schemes when substituting, as the AD1857 supports 18-bit and 20-bit words while the AD1858 is limited to 16-bit.
