Description

The LM2907N is one member of the LM2907 family which is designed as the monolithic frequency to voltage converter that can be used in (1)over/under speed sensing; (2)frequency to voltage conversion (tachometer); (3)speedometers; (4)breaker point dwell meters; (5)hand-held tachometer; (6)speed governors; (7)cruise control; (8)automotive door lock control; (9)clutch control; (10)horn control; (11)touch or sound switches. And the advantages of this device are:(1)output swings to ground for zero frequency input; (2)easy to use; VOUT e fIN c VCC c R1 c C1; (3)only one RC network provides frequency doubling.

Features of the LM2907N are:(1)ground referenced tachometer input interfaces directly; (2)with variable reluctance magnetic pickups; (3)op amp/compara-tor has floating transistor output; (4)50 mA sink or source to operate relays, solenoids, meters, or LEDs; (5)frequency doubling for low ripple; (6)tachometer has built-in hysteresis with either differential input or ground referenced input; (7)built-in zener on LM2917; (8)g0.3% linearity typical; (9)ground referenced tachometer is fully protected from damage due to swings above VCC and below ground.

The absolute maximum ratings of the LM2907N can be summarized as:(1)supply voltage:28 V;(2)supply current (zener options):25 mA;(3)collector voltage: 28 V;(4)differential input voltage tachometer:28 V;(5)differential input voltage op amp/comparator:28 V;(6)operating temperature range:-40 to +85;(7)storage temperature range:-65 to +150;(8)soldering information dual-in-line package soldering (10 seconds):260.
