The AD8422 is a high precision, low power, low noise, rail-to-railinstrumentation amplifier that delivers the best performanceper unit microampere in the industry. The AD8422 processessignals with ultralow distortion performance that is loadindependent over its full output range.
The AD8422 is the third generation development of the industry standard AD620. The AD8422 employs new process technologies and design techniques to achieve higher dynamic range andlower errors than its predecessors, while consuming less thanone-third of the power. The AD8422 uses the high performancepinout introduced by the AD8221.
Very low bias current makes the AD8422 error-free with highsource impedance, allowing multiple sensors to be multiplexedto the inputs. Low voltage noise and low current noise make theAD8422 an ideal choice for measuring a Wheatstone bridge.
The wide input range and rail-to-rail output of the AD8422bring all of the benefits of a high performance in-amp to singlesupplyapplications. Whether using high or low supply voltages,the power savings make the AD8422 an excellent choice forhigh channel count or power sensitive applications on a verytight error budget.
The AD8422 uses robust input protection that ensures reliabilitywithout sacrificing noise performance. The AD8422 has highESD immunity, and the inputs are protected from continuousvoltages up to 40 V from the opposite supply rail.
A single resistor sets the gain from 1 to 1000. The reference pincan be used to apply a precise offset to the output voltage.The AD8422 is specified from −40°C to +85°C and has typicalperformance curves to 125°C. It is available in 8-lead MSOPand 8-lead SOIC packages.
