MAX4372 Maxim, MAX4372 Datasheet - Page 3

• Manufacturer Part Number: MAX4372
• Description: Low-Cost / SOT23 / Micropower / High-Side Current-Sense Amplifier with Voltage Output
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS (continued)
(V
at T
Note 1: All devices are 100% production tested at T
Note 2: Guaranteed by PSR test.
Note 3: Guaranteed by OUT Voltage Error test.
Note 4: Output voltage is internally clamped not to exceed 12V.
Note 5: Total OUT voltage error is the sum of gain and offset voltage errors.
Note 6: Measured at I
Note 7: +6.25mV = 1/16 of +100mV full-scale voltage (C/16).
Note 8: The device will not reverse phase when overdriven.
