AD537SD/883B

Overview

The AD537SD/883B is a monolithic voltage-to-frequency converter manufactured by Analog Devices Inc. It operates within a maximum frequency of 0.15 MHz and features a maximum linear error of 0.1%. The device supports supply voltages ranging from 4.5 V to 36 V and functions in temperatures between -55 °C and 125 °C. It utilizes a CDIP-14 hermetically sealed ceramic package with side brazing, designed for military-grade reliability.

Feature Summary

• Monolithic voltage-to-frequency conversion architecture
• Hermetically sealed ceramic DIP packaging
• Military temperature range operation

Applications

• Precision instrumentation systems
• Data acquisition circuits
• Frequency modulation applications

Procurement Notes

Verify the specific suffix /883B indicates military qualification and hermetic sealing requirements. Confirm that the CDIP-14 package matches your board layout constraints. Ensure compatibility with the specified 4.5 V to 36 V supply range. Validate that the 0.1% linearity meets your system accuracy needs. Check for lead-based termination compliance if RoHS exemptions apply.

Selection Notes

Select this component when high linearity and wide dynamic range are required for voltage-to-frequency conversion. The military temperature rating makes it suitable for harsh environments. Consider the CDIP-14 package size for through-hole mounting. Evaluate the 0.15 MHz maximum frequency against your signal bandwidth requirements. Ensure the 36 V maximum supply voltage aligns with your power design.
