Figure 33. Driving the Analog Inputs
setting the bias resistor—RBIAS
Each device in this family requires an external resistor be connected from pin 14 to ground. The value of this
resistor is determined by which device is being used. Refer to Table 2 for the correct resistor value. This resistor
only dissipates less than 1 mW of power. The resistor accuracy of 1% is adequate.
