AD7952BSTZRL

Overview

The AD7952BSTZRL is a 14-bit, 1 MSPS differential PulSAR ADC from Analog Devices. It features multiple programmable input ranges: +5 V (10 V p-p), +10 V (20 V p-p), ±5 V (20 V p-p), and ±10 V (40 V p-p). Throughput reaches 1 MSPS in warp mode, 800 kSPS in normal mode, and 670 kSPS in impulse mode. The device offers an INL of ±0.3 LSB typical and SNR of 85 dB at 2 kHz. It includes a 5 V internal reference with 3 ppm/°C drift and a TEMP output. Power dissipation is 235 mW at 1 MSPS and 10 mW at 1 kSPS. It supports parallel and serial interfaces.

Feature Summary

• Configurable input ranges via pins or software for flexible signal interfacing
• Three distinct sampling modes optimizing throughput versus power consumption
• Integrated high-speed SAR architecture with no pipeline delay
• Dual interface options supporting both parallel bus and serial communication protocols

Applications

• Process controls
• Medical instruments
• High speed data acquisition
• Digital signal processing
• Instrumentation

Procurement Notes

Verify the RL suffix indicates reel packaging when sourcing. Confirm the BSTZ designation corresponds to the LQFP-48 package variant. Ensure compatibility with required supply voltages and logic levels before integration. Check for RoHS compliance documentation if environmental regulations apply to the specific manufacturing batch.

Selection Notes

Select this component for applications requiring high resolution and moderate speed. Consider the available input ranges to match signal amplitudes without external attenuation. Evaluate power constraints against the three operating modes. Verify interface requirements to determine between parallel or serial configuration based on system pin availability.

Part Context

This part belongs to the AD7952 family of 14-bit PulSAR ADCs. It shares core specifications with other variants like the AD7952BSTZ but differs in packaging format. The series is designed for precision data acquisition tasks requiring low noise and high linearity within a compact form factor suitable for dense PCB layouts.

Replacement Considerations

Direct substitutes include other AD7952 variants such as the AD7952BSTZ. Cross-referencing package dimensions and pinout compatibility is essential. Ensure replacement parts maintain the same throughput and accuracy specifications for critical performance applications.
