NOTES

1AD9100JD: 0°C to +70°C. AD9100AD: –40°C to +85°C. AD9100SD: –55°C to +125°C. DIP θJA = 38°C/W; this is valid with the device mounted flush to a

grounded 2 oz. copper clad board with 16 sq. inches of surface area and no air flow.

2The input to the AD9100 is internally clamped at ± 2.3 V. The internal input series resistance is nominally 50 Ω.

3Hold mode noise is proportional to the length of time a signal is held. For example, if the hold time (t H) is 20 ns, the accumulated noise is typically 6 µV (300 V/s ϫ

20 ns). This value must be combined with the track mode noise to obtain total noise.

4Min and max droop rates are based on the military temperature range (–55 °C to +125°C). Refer to the “Droop Rate vs Temperature” chart for min/max limits over

the commercial and industrial ranges.

Specifications subject to change without notice.
