Operating Temperature Range
Storage Temperature Range . . . . . . . . . . . . –65°C to +150°C
Temperature ranges are as follows: A, B Versions: –40°C to +85°C; S Version: –55°C to +125°C.
S Version available on AD7892-1 and AD7892-2 only.
See Terminology.
Sample tested @ +25°C to ensure compliance.
These normal mode and standby mode currents are achieved with resistors (in the range 10 kΩ to 100 kΩ) to either DGND or V
A conversion should not be initiated on the part within 30 µs of exiting standby mode.
