AD7952BCPZRL

Overview

The AD7952BCPZRL is a 14-bit, 1 MSPS PulSAR ADC fabricated on iCMOS technology. It features fully differential inputs with four programmable ranges: 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V. The device supports warp (1 MSPS), normal (800 kSPS), and impulse modes. It includes an internal 5 V reference with 3 ppm/°C drift and a TEMP output. Throughput speeds vary by mode, with power dissipation at 235 mW for 1 MSPS throughput. The part operates from −40°C to +85°C and utilizes SPI/QSPI/MICROWIRE/DSP-compatible serial or parallel interfaces.

Feature Summary

• Configurable input ranges selectable via hardware pins or software commands
• Integrated high-speed SAR architecture with no pipeline delay
• Internal voltage reference with temperature sensor output
• Flexible digital interface supporting both parallel and serial data formats

Applications

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

Procurement Notes

Verify the specific package variant against the datasheet ordering guide. Confirm that the suffix RL indicates reel packaging. Ensure the component meets RoHS standards as specified in the manufacturer documentation. Cross-reference the pinout for LFCSP-48 packages to ensure compatibility with the target PCB footprint.

Selection Notes

Select this component when a 14-bit resolution and up to 1 MSPS throughput are required. Consider the available input ranges if bipolar signals are present. Evaluate the power consumption requirements across different operating modes. Verify that the host system can support either the parallel bus or the serial configuration interface.

Part Context

This device belongs to the Analog Devices PulSAR family of analog-to-digital converters. It utilizes successive approximation register architecture built on iCMOS process technology. The series provides integrated sampling, conversion, and reference capabilities within a single chip.

Replacement Considerations

The AD7951 offers similar specifications but supports bipolar input ranges only. The AD7666 provides comparable performance with additional software-programmable input range selection.
