Its key specifi cations are given as:
1. Resolution 8 Bits
2. Total Unadjusted Error + /_ ½ LSB and + /_ 1 LSB
3. Single Supply 5 VDC
4. Low Power 15 mW
5. Conversion Time 100 μsecs
It is an 8-input multiplexed ADC, which means that it has 8 input analog signal
lines, though only one of them can be operational at a time. is is selected by three
address inputs A, B, C. Table 3. 1 shows the address bit confi guration for selecting spe-
cifi c input channels. For example, if IN0 is to act as the input, the address lines C, B and
A all have to be low; for IN1, the values of CBA is to be 001 and so on.
