* Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under "Absolute Maximum Ratings" may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operation sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
GENERAL DESCRIPTION
(Cont.)
tains this state until a transition occurs on the CMPTR output,
at which time the processor halts its timer. The resulting
timer count is the converted analog data. Integrator Zero
(the final phase of conversion) removes any residue remain-
ing in the integrator in preparation for the next
conversion.
The TC500/500A/510/514 offer high resolution (up to 17
bits) superior 50Hz/60Hz noise rejection, low power opera-
tion, minimum I/O connections, low input bias currents and
lower cost compared to other converter technologies having
similar conversion speeds.
