RV4151NB

Overview

The RV4151NB is a precision Voltage-to-Frequency (V/F) converter manufactured by Texas Instruments. It operates with a maximum frequency of 100 kHz and features a full-scale accuracy of ±50 ppm/°C. The device is housed in an 8-DIP package with dimensions of 0.300 inches (7.62 mm). It functions as a dedicated integrated circuit for converting analog voltage signals into proportional digital frequency outputs, suitable for high-precision measurement applications requiring stable conversion characteristics.

Feature Summary

• Precision voltage-to-frequency conversion capability
• High stability with low temperature coefficient
• Dedicated single-function integrated circuit design

Applications

• Analog signal digitization
• Precision measurement systems
• Data acquisition interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific revision level matches system requirements. Check for obsolete status indicators as availability may be limited. Ensure proper handling procedures are followed during storage and installation to maintain performance integrity.

Selection Notes

Select this component when a dedicated V/F conversion solution is required rather than using general-purpose ADCs. Consider the 100 kHz frequency limit and ±50 ppm/°C stability for thermal environments. Evaluate the 8-DIP package constraints against PCB layout requirements. Compare against modern alternatives if long-term supply assurance is critical.

Part Context

The RV4151NB belongs to the family of precision voltage-to-frequency converters from Texas Instruments, related to the LM231/LM331 series. These devices are designed for applications where linear conversion and temperature stability are paramount. The part represents a specialized analog front-end solution for transforming continuous voltage levels into discrete frequency domains.

Replacement Considerations

The RV4151NB is listed as an obsolete part number. Potential replacements include the LM331 or LM231 series components, which share similar functional architectures. Verify pin compatibility and electrical specifications before substituting to ensure circuit continuity.
