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

Input Noise vs. Frequency:
Voltage noise referred to the input
is dependent on gain and signal bandwidth. Figure 11 illustrates
the typical input noise in nV/√Hz of the AD210 for a frequency
range from 10 to 10 kHz.

Gain Nonlinearity vs. Output:
Gain nonlinearity is defined as the
deviation of the output voltage from the best straight line, and is
specified as % peak-to-peak of output span. The AD210B provides
guaranteed maximum nonlinearity of
±
0.012% with an output span of
±
10 V. The AD210’s nonlinearity performance is shown in Figure 12.
Gain Nonlinearity vs. Output Swing:
The gain nonlinearity
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
fraction of signal swing improves. The shape of the nonlinearity
remains constant. Figure 13 shows the gain nonlinearity of the
AD210 as a function of total signal swing.
