2 / 17 page 3-20 TELCOM SEMICONDUCTOR, INC. * 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.
