... Connecting an external resistor between this pin and ground reduces the typical conversion time to as little as 350 ns with only a small increase in linearity error. For ease of interface to microprocessors, the ADC10461, ADC10462, and ADC10464 have been designed to appear as a memory location or I/O port without the need for exter- nal interface logic ...

... On the multiple-input devices (ADC10462 and ADC10464), these pins select the analog input that will be connected to the A/D during the conversion. The input is selected based on the state of S0 and S1 when S/H makes its High-to-Low transition (See the Timing Diagrams). The ADC10464 includes both S0 and S1. The ADC10462 includes just S0, and the ADC10461 has neither Reference voltage inputs ...

... ADC1066x - Guaranteed Applications Information 1.0 MODES OF OPERATION The ADC10461, ADC10462, and ADC10464 have two basic digital interface modes. Figure 1 and Figure 2 are timing diagrams for the two modes. The ADC10462 and ADC10464 have input multiplexers that are controlled by the logic levels on pins S and S when S/H goes low ...

... De- pending upon the circuit board layout and other system considerations, more bypassing may be necessary. The ADC10461 has a single ground pin, and the ADC10462 and ADC10464 each have separate analog and digital ground pins for separate bypassing of the analog and digital supplies ...
