LM1964 Sensor Interface Amplifier
General Description
The LM1964 is a precision differential amplifier specifically
designed for operation in the automotive environment. Gain
accuracy is guaranteed over the entire automotive tempera-
ture range (-40''C to + 125''C) and is factory trimmed prior
to package assembly. The input circuitry has been specifi-
cally designed to reject tttttttmon-mode signals as much as
3V below ground on a single positive power supply. This
facilitates the use of sensors which are grounded at the
engine block while the LM1964 itself is grounded at chassis
potential. An external capacitor sets the maximum operating
frequency of the amplifier, thereby filtering high frequency
transients. Both inputs are protected against accidental
shorting to the battery and against load dump transients.
The input impedance is typically 1 Mn.
The output op amp is capable of driving capacitive loads
and is fully protected. Also, internal circuitry has been pro-
vided to detect open circuit conditions on either or both in-
puts and force the output to a "home" position (a ratio of
the external reference voltage).

Note t.. This test is performed with a 10000 source impedance.
Note 2: These parameters are guaranteed and 100% production iested.
Note 3: These parameters will be guaranteed but not 100% production tested.
Note 4: The LM1964 has been designed to common-mode to -3V, but production testing is only performed at 11V.
Note 5: Gain error is given as a percent of full-scale. Fuil-scale is defined as IV at the input and 4.5V at the output.
Note 6: For operation in ambient temperatures above 25''C the device must be derated based on a maximum junction temperature of 150'C and a thermal
resistance of 93''C/W junction to ambient.
