AD1974WBSTZ-RL

Overview

The AD1974WBSTZ-RL is a high-performance, single-chip analog-to-digital converter (ADC) featuring four differential inputs. It utilizes a multibit sigma-delta architecture to provide 24-bit resolution with sample rates up to 192 kHz. The device operates on a single 3.3 V supply and includes an integrated phase-locked loop (PLL) for clock generation, supporting low EMI design. Key electrical specifications include a dynamic range of 107 dB, -94 dB THD+N, and tolerance for 5 V logic inputs. It offers flexible digital interfaces including I2S, TDM, and left/right justified modes via an SPI control port.

Feature Summary

• Four-channel ADC with 24-bit resolution and 192 kHz maximum sample rate
• Integrated PLL for master clock generation from LRCLK or external crystal
• Low EMI design optimized for 3.3 V single-supply operation
• SPI-controllable with software power-down and clickless mute features

Applications

• Automotive audio systems
• Home theater systems
• Set-top boxes
• Digital audio effects processors

Procurement Notes

Verify the component matches the specific package type and temperature rating required for the application. Confirm that the ordering suffix corresponds to the desired tape-and-reel configuration if applicable. Ensure compatibility with the system's voltage levels and clocking requirements before integration.

Selection Notes

Select this component when a high-resolution, multi-channel ADC with integrated clock management is required. It is suitable for applications needing low electromagnetic interference and flexible serial data formats like TDM or I2S. Consider the 48-lead LQFP package constraints and thermal dissipation characteristics during PCB layout.
