LM2907/LM2917 Frequency to Voltage Converter

Check for Samples: LM2907-N, LM2917-N

FEATURES

DESCRIPTION

The LM2907, LM2917 series are monolithic

•

Ground Referenced Tachometer Input

Interfaces Directly With Variable Reluctance

Magnetic Pickups

frequency to voltage converters with a high gain op

amp/comparator designed to operate 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 in two

versions (LM2907-8, LM2917-8) and its output swings

to ground for a zero frequency input.

•

Op Amp/Comparator Has Floating Transistor

Output

50 mA Sink or Source to Operate Relays,

Solenoids, Meters, or LEDs

•

Frequency Doubling For Low Ripple

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 V_CCup to a maximum V_CEof 28V.

Tachometer Has Built-In Hysteresis With

Either Differential Input or Ground Referenced

Input

•

Built-In Zener on LM2917

±0.3% Linearity Typical

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. This

version is well suited for single speed or frequency

switching or fully buffered frequency to voltage

conversion applications.

Ground Referenced Tachometer is Fully

Protected From Damage Due to Swings Above

V_CCand Below Ground

APPLICATIONS

•

Over/Under Speed Sensing

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.

Frequency to Voltage Conversion

(Tachometer)

•

Speedometers

Breaker Point Dwell Meters

Hand-Held Tachometer

Speed Governors

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.

Cruise Control

Automotive Door Lock Control

Clutch Control

Horn Control

Touch or Sound Switches

ADVANTAGES

•

Output Swings to Ground For Zero Frequency

Input

•

Easy to Use; V_OUT= f_IN× V_CC× R1 × C1

Only One RC Network provides Frequency

Doubling

•

Zener Regulator on Chip allows Accurate and

Stable Frequency to Voltage or Current

Conversion (LM2917)
