AD7952BCPZ

Overview

The AD7952BCPZ is a 14-bit, 1 MSPS differential PulSAR ADC fabricated on iCMOS technology. It features four software- or pin-programmable input ranges: 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V. The device offers three throughput modes: warp mode (1 MSPS), normal mode (800 kSPS), and impulse mode (670 kSPS). Key performance metrics include an INL of ±1 LSB maximum, SNR of 85 dB at 2 kHz, and no missing codes. It integrates a 5 V internal reference with 3 ppm/°C drift and provides both parallel and serial interfaces compatible with SPI/QSPI/MICROWIRE standards.

Feature Summary

• Configurable analog input ranges selectable via hardware pins or serial commands
• Three distinct sampling modes optimizing for maximum speed, asynchronous operation, or power efficiency
• Integrated high-speed SAR architecture with zero pipeline delay
• Dual interface options supporting 14-bit/8-bit parallel buses and multi-standard serial protocols

Applications

• Process control systems
• Medical instrumentation
• High-speed data acquisition
• Digital signal processing
• Automated test equipment

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 48-lead LFCSP package when sourcing. Confirm that the ordering information matches the manufacturer's current datasheet revision A specifications. Ensure compatibility with system voltage requirements before procurement.

Selection Notes

Select this component for applications requiring high-resolution differential input conversion without pipeline latency. Evaluate the trade-off between warp mode throughput and impulse mode power consumption based on system thermal constraints. Verify that the host processor supports the required parallel or serial interface timing.

Part Context

This part belongs to the Analog Devices AD7952 family of PulSAR ADCs. It utilizes successive approximation register architecture to achieve 14-bit resolution at speeds up to 1 MSPS. The device is designed for precision applications requiring low noise and high linearity in a compact surface-mount package.

Replacement Considerations

The AD7952BSTZ serves as a lead-free replacement variant within the same product family. Both parts share identical electrical characteristics and pinouts but differ in packaging material compliance.
