Precision, High-Bandwidth Op Ampwww.DataSheet4U.com
General Description
The MAX9622 op amp features rail-to-rail output and
50MHz GBW at just 1mA supply current. At power-up,
this device autocalibrates its input offset voltage to less
than 100FV. It operates from a single-supply voltage of
2.0V to 5.25V.
The MAX9622 is available in a tiny 2mm x 2mm, 5-pin
SC70 package and is rated over the -40NC to +125NC
automotive temperature range.

layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
