GENERAL DESCRIPTION  
The AD8420 can operate off both single or dual supplies. It  
works well for a portable system with a limited single supply  
voltage and equally well for a system using large dual supplies.  
The AD8420 is a low cost, wide supply range amplifier that uses  
two resistors to set any gain between 1 and 1000. It is optimized  
to amplify small differential voltages in the presence of large  
common mode signals.  
Gain is set using the ratio of two resistors. A reference pin  
allows the user to offset the output voltage. This feature is useful  
when the output signal needs to be centered around a specific  
voltage, such as mid-supply.  
The AD8420 is based on a current mode architecture that gives  
it excellent input common mode range. Unlike conventional  
instrumentation amplifiers, the AD8420 can easily amplify  
signals at or even slightly below ground without requiring dual  
supplies. The AD8420 has a full rail to rail output, and the  
output voltage is completely independent of the input common  
mode voltage.  
The AD8420 is available in an 8 pin MSOP package.  
Performance is specified over the full temperature range of  
−40°C to +85°C. Part is operational from −40°C to +125°C
