Analog Inputs

3.4

Power Supply (V

SS

and V

DD

)

The comparator non-inverting and inverting inputs are

high-impedance CMOS inputs with low bias currents.

3.2

CS Digital Input

The positive power supply pin (V

DD

) is 1.6V to 5.5V

higher than the negative power supply pin (V

SS

). For

normal operation, the other pins are at voltages

between V

SS

and V

DD

.

Typically, these parts are used in a single (positive)

supply configuration. In this case, V

SS

is connected to

ground and V

DD

is connected to the supply. V

DD

will

need a local bypass capacitor (typically 0.01 碌F to

0.1 碌F) within 2 mm of the V

DD

pin. These can share a

bulk capacitor with nearby analog parts (within

100 mm), but it is not required.

This is a CMOS, Schmitt-triggered input that places the

part into a low power mode of operation.

3.3

Digital Outputs

The comparator outputs are CMOS, push-pull digital

outputs. They are designed to be compatible with

CMOS and TTL logic and are capable of driving heavy

DC or capacitive loads.
