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 (VSS and VDD)

The positive power supply pin (VDD) is 2.5V to 5.5V

higher than the negative power supply pin (VSS). For

normal operation, the output pins are at voltages

between VSS and VDD; while the input pins are at

voltages between VSS – 0.3V and VDD +0.3V.

Typically, these parts are used in a single-supply

(positive) configuration. In this case, VSS is connected

to ground and VDD is connected to the supply. VDD will

need a local bypass capacitor (typically 0.01 µF to

0.1 µF) within 2 mm of the VDD pin. These parts can

share a bulk capacitor with nearby analog parts

(typically 1 µF or larger) within 100 mm of the VDD pin.

3.4

Digital Input

The Chip Select (CS) pin is a Schmitt-triggered, CMOS

logic input. It is used to place the MCP608 op amp in a

Low-power mode, with the output(s) in a Hi-Z state.
