(1) Hysteresis is the sum +VTH − (−VTH), offset voltage is their difference. See test circuit.
(2) VOH is equal to ¾ × VCC − 1 VBE, VOL is equal to ¼ × VCC − 1 VBE therefore VOH − VOL = VCC/2. The difference, VOH − VOL, and the
mirror gain, I2/I3, are the two factors that cause the tachometer gain constant to vary from 1.0.
(3) Be sure when choosing the time constant R1 × C1 that R1 is such that the maximum anticipated output voltage at pin 3 can be reached
with I3 × R1. The maximum value for R1 is limited by the output resistance of pin 3 which is greater than 10 MΩ typically.
(4) Nonlinearity is defined as the deviation of VOUT (@ pin 3) for fIN = 5 kHz from a straight line defined by the VOUT @ 1 kHz and VOUT
10 kHz. C1 = 1000 pF, R1 = 68k and C2 = 0.22 mFd.

APPLICATIONS INFORMATION
The LM2907 series of tachometer circuits is designed for minimum external part count applications and
maximum versatility. In order to fully exploit its features and advantages let's examine its theory of operation. The
first stage of operation is a differential amplifier driving a positive feedback flip-flop circuit. The input threshold
voltage is the amount of differential input voltage at which the output of this stage changes state. Two options
(LM2907-8, LM2917-8) have one input internally grounded so that an input signal must swing above and below
ground and exceed the input thresholds to produce an output. This is offered specifically for magnetic variable
reluctance pickups which typically provide a single-ended ac output. This single input is also fully protected
against voltage swings to ±28V, which are easily attained with these types of pickups.
The differential input options (LM2907, LM2917) give the user the option of setting his own input switching level
and still have the hysteresis around that level for excellent noise rejection in any application. Of course in order
to allow the inputs to attain common-mode voltages above ground, input protection is removed and neither input
should be taken outside the limits of the supply voltage being used. It is very important that an input not go below
ground without some resistance in its lead to limit the current that will then flow in the epi-substrate diode.
Following the input stage is the charge pump where the input frequency is converted to a dc voltage. To do this
requires one timing capacitor, one output resistor, and an integrating or filter capacitor. When the input stage
changes state (due to a suitable zero crossing or differential voltage on the input) the timing capacitor is either
charged or discharged linearly between two voltages whose difference is VCC/2. Then in one half cycle of the
input frequency or a time equal to 1/2 fIN the change in charge on the timing capacitor is equal to VCC/2 × C1.
The average amount of current pumped into or out of the capacitor then is:
(1)
The output circuit mirrors this current very accurately into the load resistor R1, connected to ground, such that if
the pulses of current are integrated with a filter capacitor, then VO = ic × R1, and the total conversion equation
becomes:
VO = VCC × fIN × C1 × R1 × K
where
•
K is the gain constant—typically 1.0
(2)
The size of C2 is dependent only on the amount of ripple voltage allowable and the required response time.
CHOOSING R1 AND C1
There are some limitations on the choice of R1 and C1 which should be considered for optimum performance.
The timing capacitor also provides internal compensation for the charge pump and should be kept larger than
500 pF for very accurate operation. Smaller values can cause an error current on R1, especially at low
temperatures. Several considerations must be met when choosing R1. The output current at pin 3 is internally
fixed and therefore VO/R1 must be less than or equal to this value. If R1 is too large, it can become a significant
fraction of the output impedance at pin 3 which degrades linearity. Also output ripple voltage must be considered
and the size of C2 is affected by R1. An expression that describes the ripple content on pin 3 for a single R1C2
combination is:
(3)
It appears R1 can be chosen independent of ripple, however response time, or the time it takes VOUT to stabilize
at a new voltage increases as the size of C2 increases, so a compromise between ripple, response time, and
linearity must be chosen carefully.
As a final consideration, the maximum attainable input frequency is determined by VCC, C1 and I2:

SNAS555C –JUNE 2000–REVISED MARCH 2013
USING ZENER REGULATED OPTIONS (LM2917)
For those applications where an output voltage or current must be obtained independent of supply voltage
variations, the LM2917 is offered. The most important consideration in choosing a dropping resistor from the
unregulated supply to the device is that the tachometer and op amp circuitry alone require about 3 mA at the
voltage level provided by the zener. At low supply voltages there must be some current flowing in the resistor
above the 3 mA circuit current to operate the regulator. As an example, if the raw supply varies from 9V to 16V, a
resistance of 470Ω will minimize the zener voltage variation to 160 mV. If the resistance goes under 400Ω or
over 600Ω the zener variation quickly rises above 200 mV for the same input variation.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
