Description

45

V

CMO

This is an analog output which can be used as a reference

source and/or to set the common mode voltage of the input. It

should be bypassed with a minimum of 1 µF low ESR

capacitor in parallel with a 0.1 µF capacitor. This pin has a

nominal output voltage of 1.5V and has a 1 mA output source

capability.

43

V

RP

Top of the reference ladder. Do not drive this pin. Bypass

this pin with a 10 µF low ESR capacitor and a 0.1 µF

capacitor.

44

V

RN

Bottom of the reference ladder. Do not drive this pin.

Bypass this pin with a 10 µF low ESR capacitor and a 0.1 µF

capacitor.
