Pin Functions (S8E/FE)

COM (Pin 1/Pin 1): COM Pin is used to interface OD and

TFLAG pins to voltage control circuits. Tie this pin to the

low voltage ground, or let it float.

–IN (Pin 2/Pin 4): Inverting Input Pin. Input common

mode range is V– + 3V to V+ – 3V. Do not exceed absolute

maximum voltage range.

+IN (Pin 3/Pin 5): Noninverting Input Pin. Input common

mode range is V– + 3V to V+ – 3V. Do not exceed absolute

maximum voltage range.

V– (Pin 4, Exposed Pad Pin 9/Pin 8, Exposed Pad

Pin 17): Negative Supply Pin. Connect to V– Only. To

achieve low thermal resistance connect this pin to the

V– power plane. The V– power plane connection removes

heat from the device and should be electrically isolated

from all other power planes.

TFLAG (Pins 5, 9/Pins 9, 17): Temperature Flag Pin. The

TFLAG pin is an open drain output that sinks current when

the die temperature exceeds 145°C.

OUT (Pin 6/Pin 12): Output Pin. If this rail-to-rail output

goes below V– , the ESD protection diode will forward

bias. If OUT goes above V+, then output device diodes

will forward bias. Avoid forward biasing the diodes on the

OUT pin. Excessive current can cause damage.

V+ (Pin 7/Pin 14): Positive Supply Pin.

OD (Pin 8/Pin 16): Output Disable Pin. Active low input

disables the output stage. If left open, an internal pull-up

resistor enables the amplifier. Input voltage levels are

referred to the COM pin.

GUARD (NA/Pins 2, 3, 6, 7, 10, 11, 13, 15): Guard pins

increase clearance and creepage between other pins.

Pins 3 and 6 can be used to build guard rings around the

inputs.
