Description

1

Termination Resistor Return Pin for VP Input.

2

Noninverting Analog Input.

3

Inverting Analog Input.

4

5, 16

Positive Supply Voltage.

6

LE

Latch Enable Input Pin, Inverting Side. In compare mode (LE = low), the output tracks changes at the input

of the comparator. In latch mode (LE = high), the output reflects the input state just prior to the comparator

being placed into latch mode. LE must be driven in complement with LE.

7

LE

Latch Enable Input Pin, Noninverting Side. In compare mode (LE = high), the output tracks changes

at the input of the comparator. In latch mode (LE = low), the output reflects the input state just prior

to the comparator being placed into latch mode. LE must be driven in complement with LE.

8

Termination Return Pin for the LE/LE Input Pins.

For the ADCMP580 (CML output stage), this pin should be connected to the GND ground.

For the ADCMP581 (ECL output stage), this pin should be connected to the –2 V termination potential.

9, 12

Digital Ground Pin/Positive Logic Power Supply Terminal.

For the ADCMP580/ADCMP581, this pin should be connected to the GND pin.

13

Negative Power Supply.

14

HYS

Hysteresis Control. Leave this pin disconnected for zero hysteresis. Connect this pin to the VEE supply

with a suitably sized resistor to add the desired amount of hysteresis. Refer to Figure 9 for proper sizing

of the HYS hysteresis control resistor.

15

GND

Analog Ground.

Heat Sink

Paddle

N/C

The metallic back surface of the package is not electrically connected to any part of the circuit. It can be left

floating for optimal electrical isolation between the package handle and the substrate of the die. It can also

be soldered to the application board if improved thermal and/or mechanical stability is desired.
