Digital Timing Characteristics
Note 17: The LM12(H)454/8’s self-calibration technique ensures linearity and offset errors as specified, but noise inherent in the self-calibration process will result
in a repeatability uncertainty of
Note 18: The Throughput Rate is for a single instruction repeated continuously. Sequencer states 0 (1 clock cycle), 1 (1 clock cycle), 7 (9 clock cycles) and 5 (44
clock cycles) are used (see Figure 15 ). One additional clock cycle is used to read the conversion result stored in the FIFO, for a total of 56 clock cycles per con-
version. The Throughput Rate is f
Note 19: A military RETS specification is available upon request.
