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-

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).

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 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 MX.
