 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. 60 0 40 –20 φG = 1 20 –40 φG = 100 0 –60 –20 –80 –40 –100 –60 –120 –80 –140 10 100 1k 10k 100k FREQUENCY – Hz Figure 10. Phase Shift and Gain vs. Frequency 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. 60 50 40 30 20 10 +0.04 +8 +0.03 +6 +0.02 +4 +0.01 +2 0 0 –0.01 –2 –0.02 –4 –0.03 –6 –0.04 –10 –8 –6 –4 –2 0 +2 +4 +6 OUTPUT VOLTAGE SWING – Volts –8 +8 +10 Figure 12.

The gain versus temperature performance illustrated is for an AD210 configured as a unity gain amplifier. 0 10 100 1k 10k FREQUENCY – Hz Figure 11. Input Noise vs. Frequency 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. 400 200 G=1 0 –200 –400 –600 –800 –1000 –1200 –1400 –1600 –25 0 +25 +50 +70 +85 TEMPERATURE – °C Figure 14.
