Lm2907 Schaltung. Lm2907 n lm2917 n snas555d june 2000 revised december 2016 lm2907 and lm2917 frequency to voltage converter 1 1 features 1 ground referenced tachometer input interfaces directly with variable reluctance magnetic pickups op amp has floating transistor output 50 ma sink or source to operate relays solenoids meters or leds. Alright so i m pretty decided on using the lm2907 i still however do not fully understand the doifference between the 2917 and 2907.
The first stage of oper ation is a differential amplifier driving a positive feedback flip flop circuit. Frequency to voltage converter lm2907 datasheet lm2907 circuit lm2907 data sheet. At each zero crossing of the input signal the charge pump changes the state of capacitor c1 and provides a one shot pulse into the zener diode at pin 3.
I m going to give it an input of 12v vcc so that i can get a maximum outout of 6v vcc 2.
The lm2907 series of tachometer circuits is designed for minimum external part count applications and maximum versatility.
