External decoupling capacitors are recommended on all power pins.
Analog inputs must be driven from an operational amplifier that does not degrade the ADC performance.
External voltage on ADCREFIN is enabled by changing bits 15:14 in the ADC Reference Select register depending on
the voltage used on this pin. TI recommends TI part REF3020 or equivalent for 2.048-V generation. Overall gain
accuracy will be determined by accuracy of this voltage source.

NOTE
The temperature rating of any recommended component must match the rating of the end
product.
The ADC operation is configured, controlled, and monitored by the registers listed in
Table 4-5
