AD7874–SPECIFICATIONS
Temperature ranges are as follows: A, B Versions: –40 C to +85 C; S Version: –55 C to +125 C.
See Terminology.
Sample tested @ +25 C to ensure compliance.
Measured with respect to the REF IN voltage and includes bipolar offset error.
For capacitive loads greater than 50 pF a series resistor is required.
