LM9044 Lambda Sensor Interface Amplifier February 1995 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 temperature range (b40 C to a 125 C) and is factory trimmed prior to package assembly The input circuitry has been specifically 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 agains
