(1)

Ideal input span, does not include gain or offset error.

(2)

Measured relative to actual measured reference.

(3)

Calculated on the first nine harmonics of the input frequency.

(4)

This specification indicates the endpoint INL, not best-fit INL.

(5)

Excludes internal reference accuracy error.

(6)

Excludes internal reference temperature drift.

(7)

All specifications expressed in decibels (dB) refer to the full-scale input (FSR) and are tested with a 1-kHz input signal 0.25 dB below

full-scale, unless otherwise specified.

(8)

Bipolar ranges are ±12.288 V, ±10.24 V, ±6.144 V, ±5.12 V, and ±2.56 V.

(9)

Unipolar ranges are 0 V–12.288 V, 0 V–10.24 V, 0 V–6.144 V, and 0 V–5.12 V.
