FEATURES  
DESCRIPTION  
The LM9040 is a dual sensor interface circuit  
2
•
•
•
Single 5V Supply Operation  
consisting of two independent sampled input  
differential amplifiers designed for use with  
conventional Lambda Oxygen Sensors. The Lambda  
Sensor is used for monitoring the oxygen  
concentration in the exhaust of gasoline engines  
using catalytic after treatment and will deliver a  
voltage signal which is dependent on the air-fuel  
mixture. The gain of the amplifiers are internally set  
and can directly convert the Lambda sensor output  
voltage to a level suitable for A/D conversion in a  
system using a 5V reference.  
Common Mode Input Voltage Range of ±2V  
Differential Input Voltage Range of 50 mV to  
950 mV

Sampled Differential Input  
Switched Capacitor Low Pass Filter  
Internal Oscillator and VBB Generator  
Open Input Default Operation  
Cold Sensor Default Operation  
Low Power Consumption (42 mW max)  
The input common mode voltage range of each  
amplifier is ±2V with respect to the IC ground pin.  
This will allow the IC to connect to sensors which are  
remotely grounded at the engine exhaust manifold or  
exhaust pipe.  
Gain Set by Design Over the Operating  
Temperature Range  
APPLICATIONS  
•
•
Closed Loop Emissions Control  
Catalytic Converter Monitoring  
Each amplifier is capable of independent default  
operation should either, or both, of the leads to a  
sensor become open circuited.  
Noise filtering is provided by an internal switched  
capacitor low pass filter as part of each amplifier, and  
by external components.  
The LM9040 is fully specified over the automotive  
temperature range of −40°C to +125°C and is  
provided in a 14-pin Small Outline surface mount  
package.
