ADVFC32SH/883B

Overview

The ADVFC32SH/883B is a monolithic voltage-to-frequency and frequency-to-voltage converter compliant with MIL-STD-883. It features a maximum full-scale operating frequency of 500 kHz and offers high linearity, specified as ±0.01% at 10 kHz, ±0.05% at 100 kHz, and ±0.2% at 500 kHz. The device supports a six-decade dynamic range and accepts both voltage and current inputs. It operates within an extended temperature range of -55°C to +125°C and utilizes a TO-100 hermetically sealed package.

Feature Summary

• MIL-STD-883 compliant construction for harsh environment reliability
• High linearity performance across wide frequency ranges
• Open collector output compatible with TTL or CMOS logic levels

Applications

• Microprocessor-operated analog-to-digital converters
• High noise immunity analog data links
• Remote sensing signal transmission

Procurement Notes

Verify the specific suffix /883B indicates military screening compliance against the official Analog Devices datasheet. Confirm the package type matches the required hermetically sealed form factor. Ensure the temperature grade aligns with system requirements for the -55°C to +125°C range. Check for any recent product change notices regarding manufacturing sites.

Selection Notes

Select this component when MIL-STD-883 compliance is mandatory for the application. It is suitable for systems requiring high accuracy over wide temperature variations. Consider the open-collector output interface requirements for logic compatibility. Evaluate the need for hermetic sealing versus plastic packaging options based on environmental exposure.

Part Context

This part belongs to the ADVFC32 family of voltage-to-frequency and frequency-to-voltage converters manufactured by Analog Devices Inc. The standard commercial versions utilize plastic DIP or TO-100 packages, while the /883B variant specifically meets military standards for radiation hardness and reliability in space applications.

Replacement Considerations

The ADVFC32 is designed as a pin-for-pin replacement for VFC32 devices from other manufacturers. Verify electrical specifications and pinout compatibility before substituting.
