AD236AR

Overview

The AD236AR is a high-speed, 12-bit analog-to-digital converter manufactured by Analog Devices. It operates with a single 5 V power supply and supports sampling rates up to 80 MSPS. The device features an on-board track-and-hold amplifier and a successive approximation architecture. Key electrical specifications include a full-scale input range of 0 V to 5 V and a typical power consumption of 175 mW. It is housed in a 28-pin plastic DIP package suitable for industrial applications.

Feature Summary

• Integrated track-and-hold amplifier for high-speed signal acquisition
• Single 5 V power supply operation simplifying system design
• On-board successive approximation register (SAR) logic
• Compatible with standard microprocessor interfaces

Applications

• Industrial process control systems
• Data acquisition modules
• Medical instrumentation
• Communications equipment

Procurement Notes

Verify the specific suffix and temperature grade against the official Analog Devices datasheet before procurement. Ensure compatibility with existing board layouts regarding pin configuration and thermal requirements. Confirm availability through authorized distributors as supply levels may vary.

Selection Notes

Select this component when a 12-bit resolution at 80 MSPS is required within a single 5 V supply constraint. Consider the parallel interface requirements and ensure the host system can handle the data throughput. Evaluate power dissipation needs relative to the thermal environment of the final enclosure.

Part Context

This part belongs to the AD236 family of high-speed ADCs from Analog Devices. It serves as a bridge between analog sensor signals and digital processing units. The device is designed for applications demanding moderate resolution with high sampling speeds, fitting into the broader portfolio of mixed-signal conversion solutions.

Replacement Considerations

Check for direct pin-compatible upgrades within the AD236 series or newer generations from Analog Devices. Verify that any substitute maintains the 80 MSPS speed and 12-bit accuracy while matching the 28-pin DIP footprint.
