The AD8226 is designed to work with a very wide range of  
volta ge s. It can operate on supplies ranging from 1.2 V to  
18 V (2.4 V to 36 V s i ng l e s uppl y ) . The AD8226 comes with  
rail-to-rail output and a wide input range that includes the  
ability to go slightly below the negative supply. In addition, the  
AD8226 inputs can withstand voltages beyond the rail.

The AD8226 is perfect for multichannel, space-cons traine d  
a p p l i c a t i o n s . Being a low power and low cost amplifier allows  
multiple channels to be used.

The AD8226 has three grades. The A grade is the lower cost  
version and is specifie d for temperatures f rom −40°C to +85°C.  
The B grade is the higher performance version and is specified  
from −40°C to +85°C. The C grade version is the higher  
temperature version and is specified from −40°C to +105°C. All  
models are operational from −40°C to +125°C; behavior a t  
these temperatures is shown in the typical performance curves.  
The AD8226 is available in MSOP and SOIC packages.
