VS−/GND

Negative Power Supply Voltage. GND is for single 5 V applications.

3

−IN R

Inverting Input, Red Amplifier.

4

+IN R

Noninverting Input, Red Amplifier.

6

−OUT R

Negative Output, Red Amplifier.

7

+OUT R

Positive Output, Red Amplifier.

8, 11, 17, 24

VS+

Positive Power Supply Voltage.

9

+OUT G

Positive Output, Green Amplifier.

10

−OUT G

Negative Output, Green Amplifier.

12

+OUT B

Positive Output, Blue Amplifier.

13

−OUT B

Negative Output, Blue Amplifier.

15

+IN B

Noninverting Input, Blue Amplifier.

16

−IN B

Inverting Input, Blue Amplifier.

18

SYNC LEVEL

The voltage applied to this pin with respect to VS−/GND controls the amplitude of the sync pulses

that are applied to the common-mode voltages.

19

HSYNC

Horizontal Sync Pulse Input with Respect to Ground.

20

VSYNC

Vertical Sync Pulse Input with Respect to Ground.

22

+IN G

Noninverting Input, Green Amplifier.

23

−IN G

Inverting Input, Green Amplifier.

EPAD

Connect Exposed Paddle to Ground.
