DIP14 LM2917N-14 LM2917N-14/NOPB

Features
- Ground referenced tachometer input interfaces directlywith variable reluctance magnetic pickups
- Op amp/comparator has floating transistor output
- 50 mA sink or source to operate relays, solenoids,meters, or LEDs
- Frequency doubling for low ripple
- Tachometer has built-i- hysteresis with either differentialinput or ground referenced input
- Built-i- zener o- LM2917
- ±0.3% linearity typical
- Ground referenced tachometer is fully protected from damage due to swings above VCC and below ground
