Checking for live stock

The Texas Instruments LM331AN-NOPB is a compact yet powerful voltage-to-frequency (V-F) and frequency-to-voltage (F-V) converter integrated circuit, housed in an 8-pin PDIP package. Designed with precision and cost efficiency in mind, it delivers exceptional linearity (0.01% max), a broad operational range, from just 1 Hz up to 100 kHz, and low power consumption (approximately 15 mW at 5 V). The device operates seamlessly on a single 5-V supply, offers excellent temperature stability (±50 ppm/°C), and accommodates split-supply configurations. Its dynamic range of at least 100 dB (at 10 kHz full-scale) and compatibility with various logic outputs, including TTL and CMOS, make it a versatile solution for analogue-to-digital conversion, long-term integration, remote sensing, and more.

What Benefits Do You Get?

High-Precision Conversion: Achieves top-tier accuracy with linearity within 0.01%, ensuring consistent performance.
Wide Frequency Flexibility: Operates across a vast range—from very low (1 Hz) to high frequencies (100 kHz)—ideal for various application needs.
Low Power, Compact Design: Consumes ~15 mW at 5 V and fits into a standard through-hole PDIP-8 package—efficient in both power consumption and footprint.
Robust Temperature Stability: Maintains performance with only ±50 ppm/°C drift, supporting reliability across environments.
Wide Dynamic Range: Offers a minimum dynamic range of 100 dB at 10 kHz full scale, capturing signals over a broad amplitude spectrum.
Flexible Supply Options: Supports operation on either single or split power supplies, ranging from 4 V to 40 V, accommodating diverse system designs.
Logic Compatibility: Delivers pulse outputs compatible with TTL, CMOS, and DTL logic, making it easy to integrate with standard digital systems.
Isolation-Ready: Outputs can be routed through photo-isolators, enhancing safety and signal integrity in high common-mode environments.
