(1) The analog inputs are protected as shown below. Input voltage
magnitudes beyond the
Absolute Maximum Ratings may damage this device.
(2) To ensure accuracy, it is required that VA,
VTC, VE and VDR be well bypassed. Each
supply pin must be decoupled with separate bypass capacitors.
(3) Typical figures are at TA = 25°C, and represent most
likely parametric norms. Test limits are ensured to Texas Instrument's average
outgoing quality level (AOQL).
(4) Calculation of full-scale error for this device assumes that
the actual reference voltage is exactly its nominal value. Full-scale error for
this device, therefore, is a combination of full-scale error and reference
voltage error. For relationship between gain error and full-scale error, see
gain error in
Device Nomenclature.
