Dual, High Voltage Current Shunt Monitor
The AD8213 is a dual-channel, precision Current Sense Amplifier It features a set gain of 20 V/V, with a maximum 0.5% gain error over the entire temperature range. The buffered output voltage directly Interfaces with any typical converter. Excellent common-mode rejection from 2 V to +65 V, is independent of the 5 V supply. The AD8213 performs unidirectional current measurements across a shunt resistor in a variety of industrial and automotive applications, such as Motor Control solenoid control, or Battery Management
Special circuitry is devoted to output linearity being maintained throughout the input differential voltage range of 0 mV to 250 mV, regardless of the common-mode voltage present. The AD8213 also features additional pins that allow the user to low-pass Filter the input signal before amplifying, via an external capacitor to ground. The AD8213 has an operating temperature range of 40C to +125C and is offered in a small 10-lead MSOP package.
Applications High-side current sensing Motor Controls Transmission controls Diesel injection controls Engine management Suspension controls Vehicle dynamic controls DC-to-DC converters
