(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).
