LM2917 Frequency to Voltage Converter IC - 10 Pack
$26.73
SKU LM2917B
Now available from PMD Way is the interesting LM2917 Frequency to Voltage Converter IC in packs of ten.
The LM2917 is a monolithic frequency to voltage converter with a high gain op amp/comparator designed to switch 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 as the output swings to ground for a zero frequency input.
Features
- Ground referenced tachometer input connects directly to variable reluctance magnetic pickups
- Op amp/comparator has floating transistor output
- 50 mA sink or source to switch relays, solenoids, meters, or LEDs
- Frequency doubling for low ripple
- Tachometer has built-in hysteresis with a choice of differential input or ground referenced input
- Built-in zener
- +/-0.3% linearity typical
- Ground referenced tachometer is fully protected from swings above VCC and below ground
Advantages
- Output swings to ground for zero frequency input
- Simple to use VOUT = freq.IN 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
- Over/under speed sensing
- Frequency to voltage conversion (tachometer)
- Speedometers
- Breaker point dwell meters
- Hand-held tachometer
- Speed governors
- Cruise control
- Automotive door lock control
- Clutch control
- Horn control
- Y Touch or sound switches
