Differential output –IN 1 The AD8295 contains all the components necessary for a
precision instrumentation amplifier front end in one small
4 mm × 4 mm package. It contains a high performance
instrumentation amplifier, two general-purpose operational
amplifiers, and two precisely matched 20 kΩ resistors.
The AD8295 is designed to make PCB routing easy and
efficient. The AD8295 components are arranged in a logical
way so that typical application circuits have short routes and
few vias. Unlike most chip scale packages, the AD8295 does not
have an exposed metal pad on the back of the part, which frees
additional space for routing and vias. The logical pin arrangement and routing freedom enable the AD8295 to offer simple
pin-strapped solutions for complex systems in the equivalent
board space of a typical MSOP package. OUT A2 +IN A2 –IN 16 15 14 13 AD8295 12 A2 OUT A2
