VFC320SL/1-BSS2

Overview

The VFC320SL/1-BSS2 is a monolithic voltage-to-frequency converter manufactured by Texas Instruments. It integrates precision analog circuitry with digital logic to provide high linearity and stability. The device operates on a single supply voltage ranging from 4V to 40V, supporting industrial temperature ranges from -55°C to +125°C. Key electrical specifications include a full-scale frequency of up to 1 MHz and integral nonlinearity (INL) within ±0.1% FSR. It utilizes an SOIC-8 package for surface mount installation.

Feature Summary

• Monolithic integration of voltage-to-frequency conversion circuitry
• High accuracy with low integral nonlinearity error
• Wide single-supply voltage operational range
• Extended industrial temperature capability

Applications

• Industrial process control signal conditioning
• Precision measurement instrumentation
• Data acquisition systems requiring isolation

Procurement Notes

Verify the specific suffix BSS2 against official datasheets to confirm packaging details and tape-and-reel specifications. Ensure the operating environment matches the extended temperature rating. Confirm pinout compatibility if replacing legacy components. Check for RoHS compliance status in current production notices.

Selection Notes

Select this component when high linearity and wide dynamic range are required in a compact surface-mount package. Consider the 1 MHz maximum frequency limit for bandwidth requirements. Evaluate power dissipation within the SOIC-8 thermal constraints. Compare INL performance against system accuracy needs.

Part Context

This part belongs to the VFC320 family of voltage-to-frequency converters. It shares core architecture with other variants but differs in packaging and specific commercial/industrial grade distinctions. The family is designed for applications demanding reliable analog-to-digital interface solutions without external oscillators.

Replacement Considerations

Direct substitutes may include LM331 or VFC320 variants with compatible pinouts. Verify functional equivalence regarding reference voltage and output drive capabilities. Ensure thermal performance matches the original design constraints.
