MAX4211 Maxim, MAX4211 Datasheet - Page 21

• Manufacturer Part Number: MAX4211
• Description: The MAX4210/MAX4211 low-cost, low-power, high-side power/current monitors provide an analog output voltage proportional to the power consumed by a load by multiplying load current and source voltage
• Manufacturer: Maxim

The MAX4211 features a 1.21V bandgap reference out-
put, stable over supply voltage and temperature.
Typically, the reference output is connected to one of
