GENERAL DESCRIPTION  
The AD8426 is a dual channel, low cost, wide supply range  
instrumentation amplifier that requires only one external  
resistor to set any gain from 1 to 1000.  
bias currents are specified to facilitate open-wire detection.  
The AD8426 is designed to make PCB routing easy and  
efficient. The two amplifiers are arranged in a logical way  
so that typical application circuits have short routes and few  
vias. Unlike most chip scale packages, the AD8426 does not  
have an exposed metal pad on the back of the part, which frees  
additional space for routing and vias. The AD8426 offers two in  
amps in the equivalent board space of a typical MSOP package.  
The AD8426 is designed to work with a variety of signal  
voltages. A wide input range and rail-to-rail output allow the  
signal to make full use of the supply rails. Because the input  
range also includes the ability to go below the negative supply,  
small signals near ground can be amplified without requiring  
dual supplies. The AD8426 operates on supplies ranging from  
1.ꢀ3 V to 18 V for dual supplies and 2.2 V to ꢀ6 V for single  
supply.  
The AD8426 is ideal for multichannel, space-constrained  
industrial applications. Unlike other low cost, low power  
instrumentation amplifiers, the AD8426 is designed with a  
minimum gain of 1 and can easily handle 10 V signals. With  
its space-saving LFCSP package and 123°C temperature rating,  
the AD8426 thrives in tightly packed, zero airflow designs.  
The robust AD8426 inputs are designed to connect to real-  
world sensors. In addition to its wide operating range, the  
AD8426 can handle voltages beyond the rails. For example,  
with a 3 V supply, the part is guaranteed to withstand ꢀ3 V  
at the input with no damage. Minimum as well as maximum input  
The AD8226 is the single channel version of the AD8426.
