AD8410A/AD8411A Current-Sense Amplifiers

ADI's AD8410A is a high voltage, high bandwidth current-sense amplifier. The device features an initial gain of 20 V/V and 2.2 MHz bandwidth with a maximum ±0.13% gain error over the entire temperature range.

The AD8411A is a high-voltage, high-bandwidth current-sense amplifier. The device features an initial gain of 50 V/V and 2.7 MHz bandwidth with a maximum ±0.15% gain error over the entire temperature range.

The buffered output voltage from these devices directly interfaces with any typical converter. The AD8410A and AD8411A have a minimum DC common-mode rejection ratio (CMRR) of 123 dB from -2 V to +70 V. These amplifiers perform bidirectional current measurements across a shunt resistor in various industrial and automotive applications.

The available evaluation boards are designed for easy configuration of different modes of operation and allow flexibility with loads. A shunt resistor (R1), with a maximum standard size of 2818, can be soldered to both boards.
