No Internal Connection

The MCP6021 in the 8-pin TSSOP package is only available for I-temp (Industrial Temperature) parts.

The MCP6021R is only available in the 5-pin SOT-23 package, and for E-temp (Extended Temperature) parts.

3.1 Analog Outputs

The op amp output pins are low-impedance voltage

sources.

3.4 Chip Select Digital Input (CS)

This is a CMOS, Schmitt-triggered input that places the

part into a low power mode of operation.

3.2 Analog Inputs

The op amp non-inverting and inverting inputs are high-

impedance CMOS inputs with low bias currents.

3.3 Reference Voltage (VREF, )

MCP6021 and MCP6023

Mid-supply reference voltage provided by the single op

amps (except in SOT-23-5 package). This is an

unbuffered, resistor voltage divider internal to the part.

3.5 Power Supply (VSS and VDD)

The positive power supply pin (VDD) is 2.5V to 6.0V

higher than the negative power supply pin (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 a bypass capacitor.
