VFC320BP

Overview

The VFC320BP is a monolithic voltage-to-frequency and frequency-to-voltage converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 6V to 40V. The device features a full-scale frequency of 1 MHz with an integral nonlinearity (INL) of ±0.1% FSR at that frequency. It is housed in a 14-pin PDIP package and supports surface mount or through-hole installation. The component functions as a CMOS-based analog special function converter suitable for industrial applications.

Feature Summary

• Provides bidirectional conversion between analog voltage signals and digital frequency outputs
• Delivers high linearity performance across a wide dynamic range
• Supports six-decade dynamic range for versatile signal processing

Applications

• Industrial process control systems requiring precise signal isolation
• Data acquisition modules converting sensor voltages to frequency
• Frequency modulation circuits in communication equipment

Procurement Notes

Verify the specific suffix BP indicates the PDIP-14 package configuration when ordering. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check datasheet specifications for operating temperature ranges and supply voltage limits before integration. Ensure compatibility with existing PCB footprint designs for the 14-pin dual in-line package.

Selection Notes

Select this component when high linearity and wide dynamic range are required for V/F or F/V conversion. Consider the 1 MHz full-scale frequency limit for application bandwidth requirements. Evaluate the single-supply operation capability against system power constraints. Compare INL specifications against other converters if higher precision at lower frequencies is needed.

Part Context

The VFC320 belongs to the VFC320 series of voltage-to-frequency converters. It is part of Texas Instruments' portfolio of analog special function integrated circuits. The device complements other frequency conversion solutions by offering a cost-effective method for analog-to-digital interface tasks without external timing components.
