GENERAL DESCRIPTION  
The AD8278 is a general-purpose difference amplifier intended  
for precision signal conditioning in power critical applications  
that require both high performance and low power. The AD8278  
provides exceptional common-mode rejection ratio (80 dB) and  
high bandwidth while amplifying signals well beyond the supply  
rails. The on-chip resistors are laser-trimmed for excellent gain  
accuracy and high CMRR. They also have extremely low gain  
drift vs. temperature.  
The AD8278 can be used as a difference amplifier with G = ½  
or G = 2. It can also be connected in a high precision, single-  
ended configuration for non-inverting and inverting gains of  
−½, −2, +3, +2, +1½, +1, or +½. The AD8278 provides an  
integrated precision solution that has a smaller size, lower cost,  
and better performance than a discrete alternative.  
The AD8278 operates on single supplies (2.0 V to 36 V) or dual  
supplies ( 2 V to 18 V). The maximum quiescent supply current  
is 200 μA, which makes it ideal for battery-operated and portable  
systems.  
The common-mode range of the amplifier extends to almost  
triple the supply voltage (for G = ½), making it ideal for single-  
supply applications that require a high common-mode voltage  
range. The internal resistors and ESD circuitry at the inputs also  
provide overvoltage protection to the op amp.  
The AD8278 is available in the space-saving 8-lead MSOP  
and SOIC packages. It is specified for performance over the  
industrial temperature range of −40°C to +85°C and is fully  
RoHS compliant.
