ADVFC32BH

Overview

The ADVFC32BH is a monolithic voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter manufactured by Analog Devices Inc. It operates with a full-scale frequency range up to 500 kHz and supports both voltage and current inputs. The device features high linearity, specified at ±0.01% maximum error at 10 kHz full scale, and offers a 6-decade dynamic range. It utilizes a charge balancing circuit technique for accurate conversion. The ADVFC32BH is housed in a hermetically sealed TO-100 (H-10A) package and is rated for an operating temperature range of -25°C to +85°C.

Feature Summary

• Provides high linearity performance with minimal nonlinearity error across the operating frequency range.
• Supports flexible input configurations including unipolar/bipolar voltage or current inputs for V/F conversion.
• Features TTL/CMOS-compatible open collector output suitable for direct logic interfacing.

Applications

• Microprocessor-operated analog-to-digital converter front ends requiring high resolution.
• High noise immunity analog data links utilizing optocouplers for signal transmission.
• Industrial measurement systems requiring precise frequency modulation of sensor signals.

Procurement Notes

Verify that the specific part number matches the required temperature grade and package style. Confirm that the TO-100 hermetically sealed package aligns with system environmental requirements. Ensure compatibility with existing design constraints regarding supply voltage ranges and decoupling practices before finalizing procurement orders.

Selection Notes

Select this component when high accuracy and wide dynamic range are critical for signal conditioning applications. Consider the TO-100 package if hermetic sealing is necessary for the operational environment. Evaluate the need for external calibration components to optimize temperature drift performance in precision measurement circuits.

Part Context

The ADVFC32 series serves as a pin-for-pin replacement for legacy VFC32 devices from other manufacturers. It is designed for applications demanding reliable monolithic construction and low cost. The BH variant specifically targets industrial temperature ranges within a robust metal can package, distinguishing it from commercial plastic DIP options.

Replacement Considerations

The ADVFC32BH is explicitly intended as a pin-for-pin replacement for VFC32 devices from other manufacturers. Verify mechanical footprint compatibility and electrical specifications against legacy parts before substitution.
