MAX4073T Maxim, MAX4073T Datasheet - Page 3

• Manufacturer Part Number: MAX4073T
• Description: The MAX4073 low-cost, high-side current-sense amplifier features a voltage output that eliminates the need for gain-setting resistors making it ideal for cell phones, notebook computers, PDAs, and other systems where current monitoring is crucial
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS (continued)
(V
at T
Note 1: All devices are 100% production tested at T
Note 2: Inferred from PSRR test.
Note 3: Inferred from OUT Voltage Error test.
Note 4: Total OUT Voltage Error is the sum of the gain and offset errors.
Note 5: 6.25mV = 1/16 of 100mV full-scale sense voltage.
Note 6: Output settles to within 1% of final value.
Note 7: The device will not experience phase reversal when overdriven.
