For normal operation, the other pins are between VSS and VDD. 3.2Analog Inputs Typically, these parts are used in a single (positive) supply configuration. In this case, V The noninverting and inverting inputs (V SS is connected to IN+, VIN–, …) are high-impedance CMOS inputs with low bias ground and VDD is connected to the supply. VDD wil need bypass capacitors. currents. 2009-2011 Microchip Technology Inc.
