Applications Information (Continued)

If CS goes low before the rising edge of SCLK, an additional

(fourth) zero bit may be captured by the next falling edge of

SCLK.

3.0 ADC121S101/101S101/081S101 TRANSFER

FUNCTION

The output format of the ADC121S101/101S101/081S101 is

straight binary. Code transitions occur midway between suc-

cessive integer LSB values. The LSB widths for the

ADC121S101 is V

DD / 4096; for the ADC101S101 the LSB

width is V

DD / 1024; for the ADC081S101, the LSB width is

/ 256. The ideal transfer characteristic for the

ADC121S101 and ADC101S101 is shown in Figure 6, while

the ideal transfer characteristic for the ADC081S101 is

shown in Figure 7.
