Gain vs. Temperature:

Figure 14 illustrates the AD210’s

gain vs. temperature performance. The gain versus temperature

performance illustrated is for an AD210 configured as a unity

gain amplifier.

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.
