LM9044 Lambda Sensor Interface Amplifier
General Description
The LM9044 is a precision differential amplifier specifically
designed for operation in the automotive environment. Gain
accuracy is guaranteed over the entire automotive tempera-
ture range (

C) and is factory trimmed prior
to package assembly. The input circuitry has been specifi-
cally designed to reject common-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 LM9044 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 M
X
.
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).
