AD8211
APPLICATION NOTES
OUTPUT LINEARITY
In all current sensing applications, and especially in automotive
and industrial environments where the common-mode voltage
can vary significantly, it is important that the current sensor
maintain the specified output linearity, regardless of the input
differential or common-mode voltage. The AD8211 contains
specific circuitry on the input stage, which ensures that even
when the differential input voltage is very small, and the
common-mode voltage is also low (below the 5 V supply),
the input-to-output linearity is maintained. Figure 24 shows
the input differential voltage vs. the corresponding output
voltage at different common modes.

Figure 24. Gain Linearity Due to Differential and Common-Mode Voltage
Regardless of the common mode, the AD8211 provides a
correct output voltage when the input differential is at least
2 mV, which is due to the voltage range of the output amplifier
that can go as low as 33 mV typical. The specified minimum
output amplifier voltage is 100 mV to provide sufficient guard-
bands. The ability of the AD8211 to work with very small
differential inputs, regardless of the common-mode voltage,
allows for more dynamic range, accuracy, and flexibility in any
current sensing application.
