LM2907 Frequency To Voltage Converters IC In Pakistan
SKU: SKU: DBS26,TMD,Th,KRT
The op amp/comparator is fully compatible with the tachometer and has a floating transistor as its output. This feature allows either a ground or supply referred load of up to 50 mA. The collector may be taken above VCC up to a maximum VCE of 28V. The two basic configurations offered include an 8-pin device with a input and an internal connection between the tachometer output and the op amp non-inverting input. This version is well suited for single speed or frequency switching or fully buffered frequency to voltage conversion applications. The more versatile configurations provide differential tachometer input and uncommitted op amp inputs. With this version the tachometer input may be floated and the op amp becomes suitable for active filter conditioning of the tachometer output. Both of these configurations are available with an active shunt regulator connected across the power leads. The regulator clamps the supply such that stable frequency to voltage and frequency to current operations are possible with any supply voltage and a suitable resistor. Features 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-In Hysteresis With Either Differential Input or Ground Referenced Input Built-In Zener on LM2917 0.3% Linearity Typical Ground Referenced Tachometer is Fully Protected From Damage Due to Swings Above VCC and Below Ground Advantages Output Swings to Ground For Zero Frequency Input Easy to Use; VOUT= fIN VCC R1 C1 Only One RC Network provides Frequency Doubling Zener Regulator on Chip allows Accurate and Stable Frequency to Voltage or Current Conversion (LM2917)
