For R = 5k use Beckman Instruments #694-3-R10k resistor array or equivalent.

NOTE: High R values affect the input BW of ADC due to the (R ∗ CIN of ADC) time constant. Therefore, for different

applications the R value needs to be selected as a tradeoff between AIN settling time and power dissipation.
