AD210 Phase Shift:
Figure 10 illustrates the AD210’s low phase shift
+0.04 +8
and gain versus frequency. The AD210’s phase shift and wide
+0.03 +6
bandwidth performance make it well suited for applications like power monitors and controls systems.

–200 Gain Nonlinearity vs. Output:
Gain nonlinearity is defined as the
–400
deviation of the output voltage from the best straight line, and is specified as % peak-to-peak of output span. The AD210B provides
–600
guaranteed maximum nonlinearity of ± 0.012% with an output span of
–800
±10 V. The AD210’s nonlinearity performance is shown in Figure 12.
–1000 Gain Nonlinearity vs. Output Swing:
The gain nonlinearity
GAIN ERROR – ppm of Span –1200
of the AD210 varies as a function of total signal swing. When the output swing is less than 20 volts, the gain nonlinearity as a
–1400
fraction of signal swing improves. The shape of the nonlinearity
–1600
remains constant. Figure 13 shows the gain nonlinearity of the
–25 0 +25 +50 +70 +85
AD210 as a function of total signal swing.
