Analog Devices rolls highly accurate current sense amplifier
September 08, 2010 // Christoph Hammerschmidt
Analog Devices has introduced a new high-voltage amplifier for current sensing applications. The AD8207 zero-drift, high-voltage, bi-directional current sense amplifier meets the robust performance and quality requirements for motor and solenoid control in industrial and automotive applications. The vendor claims the device is the industry's most accurate current sense amplifier.
The product features temperature accuracy specified at a maximum of 1 μV/°C offset drift over the automotive temperature range of -40 degrees C to 125 degrees C. According to Analog Devices, this represents a 5-fold improvement over competing devices.
The architecture of the AD8207 accurately amplifies small differential current shunt voltages in the presence of rapidly changing common-mode voltages ranging from -4 V to 65 V. The new current sense amplifier rejects PWM (pulse width modulation) input common-mode voltages, while the zero-drift architecture yields the lowest offset drift performance available today.
