Zero-Drift, Programmable Instrumentation Amplifier with  
Diagnostics  
General Description  
Features  
Typical Values unless otherwise noted, TA = 25°C  
The LMP8358 is a precision programmable-gain instrumen-  
tation amplifier in National's LMP® precision amplifier family.  
Its gain can be programmed to 10, 20, 50, 100, 200, 500, or  
1000 through an SPI-compatible serial interface or through a  
parallel interface. Alternatively, its gain can be set to an arbi-  
trary value using two external resistors. The LMP8358 uses  
patented techniques to measure and continuously correct its  
input offset voltage, eliminating offset drift over time and tem-  
perature and the effect of 1/f noise. Its ground-sensing CMOS  
input features a high CMRR and low input bias currents. It is  
capable of sensing differential input voltages in a common-  
mode range that extends from 100mV below the negative  
supply to 1.4V below the positive supply, making it an ideal  
solution for interfacing with ground-referenced sensors, sup-  
ply-referenced sensor bridges, and any other application re-  
quiring precision and long-term stability. Additionally, the  
LMP8358 includes fault detection circuitry to detect open and  
shorted inputs and deteriorating connections to the signal  
source. Other features that make the LMP8358 a versatile  
solution for many applications are its rail-to-rail output, low  
input voltage noise and high gain-bandwidth product.
