AD7247JR

Overview

The AD7247JR is a dual 12-bit digital-to-analog converter (DAC) from Analog Devices, housed in a 24-lead SOIC package. It features a parallel interface and operates within a supply voltage range of 10.8 V to 16.5 V. The device supports a sampling rate of 125 kS/s with a settling time of 8 µs. Designed for industrial environments, it functions between -55°C and +125°C. Power dissipation is rated at 300 mW. This component integrates internal or external reference capabilities and is classified as a data converter IC.

Feature Summary

Dual-channel 12-bit resolution architecture
Parallel word input loading interface
Extended industrial temperature range (-55°C to +125°C)
8 µs settling time with 125 kS/s sampling rate

Applications

Industrial process control systems
Data acquisition modules requiring high stability
Precision instrumentation interfaces

Procurement Notes

Verify the discontinuation status prior to procurement, as the AD7247JR is listed as obsolete by the manufacturer. Confirm RoHS compliance requirements, as specific listings indicate non-compliant variants may exist. Ensure the SOIC-24 package footprint matches the target PCB design. Validate that the operating temperature range meets the specific environmental constraints of the application.

Selection Notes

Select this component when dual-channel 12-bit conversion with parallel interfacing is required. Compare against the AD7247JNZ for through-hole alternatives or the AD7247AARZ for improved performance specifications. Ensure the system power supply accommodates the 10.8 V to 16.5 V range. Verify thermal management capabilities given the 300 mW power dissipation rating in the SOIC package.

Part Context

The AD7247JR belongs to the AD7247 family of DACPORT devices. It shares architectural similarities with the AD7237 series but offers enhanced precision. The JR suffix denotes the plastic SOIC package variant. This part is distinct from video encoders like the AD724JRZ, which serves a different function despite similar naming conventions.
