Product Summary

The NTE995M (8--lead DIP) is a monolithic frequency to voltage converter 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.

  • Output swing to GND for zero frequency input
  • Easy-to-use: VOUT = fIN x VCC x R1 x C1
  • Only one RC network provides frequency doubling
  • Zener regulator on chip allows accurate and stable frequency to voltage or current conversion
  • Ground referenced tachometer input interfaces directly with variable reluctance magnetic pickups
  • OP amp/comparator has floating transistor output
  • 50mA sink or source to operate relays, solenoids, meters or LEDs
  • Frequency doubling for low ripple
  • Tachometer has built--in hysteresis with either differential input or ground referenced input
  • Built--in zener diode
  • &plusnm;0.3% linearity typical
  • Ground referenced tachometer is fully protected from damage due to swings above VCC and below GND
  • Supply voltage, VCC: 28V
  • Supply current (zener options): 25mA
  • Collector voltage: 28V
  • Differential input voltage tachometer: 28V
    OP amp/comparator: 28V
  • Input voltage range tachometer: &plusnm;28V
    OP amp/comparator: 0.0V to +28V
  • Power dissipation¹, PD: 200mW
  • Operating temperature range, Topr: --40° to +85°C
  • Storage temperature range, Tstg: --65° to +150°C
  • Lead temperature, TL (soldering, 10sec) 260°C, (vapor phase, 60sec) 215°C,(infrared, 15sec) 220°C
Pricing and availability: Please note that all prices are subject to change without prior notice. Prices advertised on this site are for online orders only. Prices on some items may differ from those advertised in RadioShack stores. All merchandise may not be available at all stores, and all stores may not participate in all sales promotions. We recommend you contact the store to confirm product availability and price.

Disclaimer: 1. For operation in ambient temperatures above 25°C, the device must be derated based on a +150°C maximum junction temperature and a thermal resistance of +101°C/W junction to ambient for the NTE995M, and +79°C/W junction to ambient for the NTE995.
