AD8622ARMZ-REEL is an Analog Devices operational amplifier.
The device is specified at Two precision amplifiers channels.
The manufacturer positions the series this way: Low offset voltage: 125 μV max Supply current: 215 μA/amp typ Input bias current: 200 pA max Low input offset voltage drift: 1.2 μV/ degreesC max Low voltage noise: 11 nV/√Hz Operating temperature range: -40 degreesC to +125 degreesC Rail-to-rail output swing Unity gain stable +/-2.5 V to +/-15 V operation The AD8622.
Its advantage is that the specification is backed by a published data sheet, so the part can be designed into production equipment without further characterisation.
Its advantage is the specified linearity and drift, which set the error budget of the channel.
Within the family, this ordering code is the one specified for Two precision amplifiers channels.
It is used in sensor signal conditioning and instrumentation, where the function has to behave predictably over the life of the equipment.
