NOTES
1Temperature range is as follows: A and B Versions: –40
°C to +85°C.
2Common-mode voltage. The input signal can be centered on any choice of dc common-mode voltage as long as this value is in the range specified in Figures 8 and 9.
3See Terminology section.
4A 200 mV p-p sine wave, varying in frequency from 1 kHz to 200 kHz is coupled onto V
DD. A 2.2 nF capacitor is used to decouple VDD to GND.
5If the input spans of V
IN+ and VIN– are both VREF, and they are 180
° out of phase, the differential voltage is 2
VREF.
6The AD7450 is functional with a reference input from 100 mV and for V
DD = 5 V, the reference can range up to 3.5 V (see References section).
7The AD7450 is functional with a reference input from 100 mV and for V
DD = 3 V, the reference can range up to 2.2 V (see References section).
8Sample tested @ 25
°C to ensure compliance.
9See Serial Interface section.
10See Power Versus Throughput Rate section.
11Measured with a midscale dc input.
