Bidirectional, High-Side, Current-Sense Amplifiers with Reference

Maxim Integrated 

MAX4069–MAX4072

Bidirectional, High-Side, Current-Sense

Amplifiers with Reference

Electrical Characteristics (continued)

(VRS+ = VRS- = VCC = 2.7V to 24V, VSENSE = VRS+ - VRS- = 0V, IREFOUT = 0, VSHDN = VCC, VGSEL = GND, VREFIN = 2.5V

(MAX4072), TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C and at VCC = VRS+ = 12V.) (Notes 1, 2)
