MAX9643
60V High-Speed Precision Current-Sense Amplifier
Typical Operating Characteristics (continued)
(VCC = 5V, VRS+ = VRS- = 12V, TA = -40NC to +125NC, unless otherwise noted. All devices are 100% production tested at TA = +25NC.
Temperature limits are guaranteed by design and/or characterization.)
