TERMINAL FUNCTIONS (UCC27527)

TERMINAL

I/O

FUNCTION

NUMBER

NAME

1

INA-

I

Inverting Input to Channel A: when Channel A is used in Non-Inverting

configuration connect INA- to GND in order to Enable Channel A output, OUTA held

LOW if INA- is unbiased or floating.

2

INB-

I

Inverting Input to Channel B: when Channel B is used in Non-Inverting

configuration connect INB- to GND in order to Enable Channel B output, OUTB held

LOW if INB- is unbiased or floating.

3

GND

-

Ground: All signals referenced to this pin.

4

OUTB

I

Output of Channel B

5

VDD

O

Bias Supply Input

6

OUTA

I

Output of Channel A

7

INB+

O

Non-Inverting Input to Channel B: When Channel B is used in Inverting

configuration connect INB+ to VDD in order to Enable Channel B output, OUTB held

LOW if INB+ is unbiased or floating.

8

INA+

I

Non-Inverting Input to Channel A: When Channel A is used in Inverting

configuration connect INA+ to VDD in order to Enable Channel A output, OUTA held

LOW if INA+ is unbiased or floating.
