LM Datasheet(PDF) – National Semiconductor (TI)

Both of these configurations are available with an active. This version is well suited for single speed or frequency switching or fully buffered frequency to voltage conversion applications.

Feb 4, 1. The more versatile configurations provide differential ta- chometer input and uncommitted op amp inputs. Quote of the day. Both of these configurations are available with an active shunt regulator connected across the power leads. Hello, The datasheet tells you that C1 can have a minimum value of pF. The tachom- eter uses a charge pump technique and offers frequency doubling for low ripple, full input protection in two versions LM, LM and its output swings to ground for a zero frequency input.

The two basic configurations offered include an 8-pin device with a ground referenced tachometer input and an internal connection between the tachometer output and the op amp non-inverting input.

It is ridiculous to think that chip transistors operate up to 10kHz. Any idea on how the slope can be shifted to measure frequency upto 15khz 3. Feb 2, 2 0. Do you already have an account? Discussion in ‘ General Electronics Chat ‘ started by deepika.

Apr 5, 18, 3, Feb 4, 2. The two basic configurations offered include an 8-pin device. Yes, my password is: Feb 4, 5.

Jan 29, 6, 1, Jan 3, Your name or email address: With this version the tachometer input may be floated and the op amp becomes suitable for active filter conditioning of the tachom- fatasheet output. Precision two-shot output frequency. If any Simulation model is available, that would be helpful.

Need to know if the IC supports upto 15khz. Feb 4, 4. May 20, 1, LM convert frequency Posted by beirao in forum: You havean artificial problem. This feature allows either a ground or supply referred load of up to 50 mA. The more versatile configurations provide differential ta. LM, LM and its output swings to ground for a. No, create an account now. The datasheet does not mention the threshold but has been tested for linearity upto 10khz.

Maximum Transistor Frequency Posted by Druzyek in forum: Understanding Automatic Gain Control How do designers cope with a system that has highly variable input amplitude yet requires fairly constant output amplitude?

LM/LM – Maximum Frequency supported | All About Circuits

The LM, LM series are monolithic frequency to. 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.

Tachometer Linearity vs R1.
