NTE995 & NTE995M Integrated Circuit Frequency–to–Voltage Converter
Description: The NTE995 (14–Lead DIP) and NTE995M (8–Lead DIP) are monolithic frequency to voltage converters with a high gain OP amp/comparator designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate.
The tachometer uses a charge pump technique and offers frequency doubling for low ripple, full input protection, and its output swings to GND for a zero frequency input.
Advantages: D Output Swing to GND for Zero Frequency Input D Easy to Use: VOUT = fIN x VCC x R1 x C1 D Only One RC Network Provides Frequency Doubling D Zener
Regulator On Chip Allows Accurate and Stable Freq...
