Calibrate/Chip Select Digital Input

This input (CAL/CS, …) is a CMOS, Schmitt-triggered

input that affects the calibration and low power modes

of operation. When this pin goes high, the part is placed

into a low power mode and the output is high-Z. When

this pin goes low, a calibration sequence is started

(which corrects VOS). At the end of the calibration

sequence, the output becomes low impedance and the

part resumes normal operation.

An internal POR triggers a calibration event when the

part is powered on, or when the supply voltage drops

too low. Thus, the MCP652 parts are calibrated, even

though they do not have a CAL/CS pin.

Exposed Thermal Pad (EP)

There is an internal connection between the Exposed

Thermal Pad (EP) and the VSS pin; they must be con-

nected to the same potential on the Printed Circuit

Board (PCB).

This pad can be connected to a PCB ground plane to

provide a larger heat sink. This improves the package

thermal resistance (

θJA).
