†Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the

device. This is a stress rating only and functional operation of the device at those or any other conditions, above

those indicated in the operational listings of this specification, is not implied. Exposure to maximum rating conditions

for extended periods may affect device reliability.

(Note 8)

Note 1:

This parameter is ensured by design and not 100% tested.

This parameter is ensured by characterization and not 100% tested.

REFIN- must be connected to ground for single-ended measurements.

Full-Scale Range (FSR) = 2 x VREF/GAIN.

This input impedance is due to the internal input sampling capacitor and frequency. This impedance is measured

between the two input pins of the channel selected with the input multiplexer.

Applies to all analog gains. Offset and gain errors depend on analog gain settings. See Section 2.0 “Typical

Performance Curves”.

INL is the difference between the endpoints line and the measured code at the center of the quantization band.

DIDD is measured while no transfer is present on the SPI bus.

An external buffer is recommended for external use.

10: Start-up Time is the reaction time to the SPI command.

11: Settling Time depends on bypass caps on REFIN+/OUT pin.
