Figure 8-8 shows possible layout implementations for

an application to support the quad and dual options on

the same PCB.

Dual Devices.

PCB Area Requirements

In some applications, PCB area is a criteria for device

selection. Table 8-2 shows the package dimensions

and area for the different package options. The table

also shows the relative area factor compared to the

smallest area. For space critical applications, the QFN

package would be the suggested package.

RESISTOR TEMPCO

Characterization curves of the resistor temperature

coefficient

(Tempco)

are

shown

Figure 2-10,

Figure 2-21, Figure 2-32, and Figure 2-43.

These curves show that the resistor network is

designed to correct for the change in resistance as

temperature increases. This technique reduces the

end-to-end change in RAB resistance.

8.5.4

HIGH VOLTAGE TOLERANT PINS

High Voltage support (VIHH) on the Serial Interface pins

supports

user

configuration

the

Nonvolatile

EEPROM, Write Protect, and WiperLock feature.

Note 1: Does not include recommended land

pattern dimensions.

2: These packages are for the Quad output

devices (MCP44x1).

Note:

In many applications, the High Voltage will

only be present at the manufacturing

stage so as to “lock” the Nonvolatile wiper

value (after calibration) and the contents

of the EEPROM. This ensures that since

High Voltage is not present under normal

operating conditions, that these values

can not be modified.
