Current sense amplifier achieves high accuracy for industrial, automotive applications

Norwood, Mass.— Analog Devices Inc. claims its latest current sense amplifier achieves the industry’s highest accuracy for industrial and automotive applications.

Well-suited for a variety of PWM closed-loop current control systems, ADI’s AD8207 high-voltage current sense amplifier is said to be the first to deliver a max 1 µV/°C offset temperature drift while featuring negative common-mode voltage operation and high bandwidth.

Key highlights:

• Provides low-drift current measurement for closed-loop motor control in safety critical automotive applications, such as electric power steering and advanced braking.
• Enables accurate current measurements to control solenoids and actuators in industrial applications.
• Input common-mode voltage range:
• −4 V to +65 V operating (5 V supply)
• −4 V to +35 V operating (3.3 V supply)
• −25 V to +75 V input survival
• Offset drift is typically less than 500 nV/ºC and gain drift is below 10 ppm/º C.
• 80 dB CMRR (common-mode rejection ratio) from dc to 100 kHz.
• Meets AEC-Q100 standards. Tested for EMI (electromagnetic interference) compliance.
• Adjustable output offset is effective for bi-directional current measurements.
