AD7853ARSZ-REEL7

Overview

The AD7853ARSZ-REEL7 is a 12-bit, single-channel Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It utilizes a Successive Approximation Register (SAR) architecture and operates from a single 3 V to 5.5 V supply. The device supports a throughput rate of 200 kSPS with a typical power dissipation of 12 mW at 3 V. It features a pseudo-differential input range of 0 V to VREF and includes system and self-calibration capabilities. The component communicates via a flexible serial interface compatible with SPI/QSPI/8051/microprocessor standards and is housed in a 24-lead SSOP package.

Feature Summary

• Integrated system and self-calibration mechanisms ensure accurate operation over time and temperature variations.
• Flexible serial interface supports multiple communication protocols including SPI, QSPI, 8051, and microprocessor modes.
• Automatic power-down functionality reduces energy consumption after each conversion cycle.
• Pseudo-differential sampling scheme provides robust signal acquisition capabilities.

Applications

• Battery-powered systems such as personal digital assistants and mobile communications devices
• Medical instruments requiring precise analog signal digitization
• Instrumentation and control systems for industrial automation
• High-speed modems for data transmission applications

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and reel specifications. Confirm that the component meets current environmental compliance standards required for your assembly process. Ensure compatibility with existing inventory management systems regarding part identification codes.

Selection Notes

Select this component when a 12-bit resolution and 200 kSPS throughput are required within a single-supply environment. Consider the AD7853L variant if lower power consumption is prioritized over maximum speed. Verify that the serial interface mode aligns with the host controller's available pins and timing constraints.

Part Context

This component belongs to the AD7853 family of high-speed, low-power sampling ADCs. The family includes variants optimized for different performance trade-offs, such as the AD7853L for reduced power usage. These devices share common architectural features like SAR conversion and integrated calibration logic.
