Note 1: Input current is a function of applied voltage on the analog input channels. For a given input
voltage, Vin, the input leakage is approximately equal to (8.181 * Vin – 12) µA.
Note 2: Maximum throughput when scanning is machine dependent.
Note 3: The ADS7871 converter only returns 13 bits (0 to 8,192 codes) in single-ended mode.
Note 4: Extrapolating the long term drift accuracy specifications will provide the approximate long term drift
of the intermediate input ranges.

Note 6: Zero-scale offsets may result in a fixed zero-scale error producing a "dead-band” digital input code
region. In this case, changes in digital input code at values less than 0x040 may not produce a
corresponding change in the output voltage. The offset error is tested and specified at code 0x040.
