13 / 34 page  © 2009 Microchip Technology Inc. DS22142A-page 13 MCP6071/2/4 3.0 PIN DESCRIPTIONS Descriptions of the pins are listed in Table 3-1. TABLE 3-1: PIN FUNCTION TABLE 3.1 Analog Outputs The output pins are low-impedance voltage sources. 3.2 Analog Inputs The non-inverting and inverting inputs are high- impedance CMOS inputs with low bias currents. 3.3 Power Supply Pins The positive power supply (VDD) is 1.8V to 6.0V higher than the negative power supply (VSS). For normal operation, the other pins are at voltages between VSS and VDD. Typically, these parts are used in a single (positive) supply configuration. In this case, VSS is connected to ground and VDD is connected to the supply. VDD will need bypass capacitors. 3.4 Exposed Thermal Pad (EP) There is an internal electrical connection between the Exposed Thermal Pad (EP) and the VSS pin; they must be connected to the same potential on the Printed Circuit Board (PCB).
