NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

Pin Description

EL8171/EL8172

PIN NAME

PIN FUNCTION

1

ENABLE

Active Low. When pulled up above 2V, the in-amp conserves 3µA disabled supply current and the output is

in a high impedance state. An internal pull down defines the ENABLE low when left floating.

2

IN-

Inverting (IN-) and non-inverting (IN+) high impedance input terminals. The input terminals are equivalent to

the gate of PMOS transistor.

3IN+

5

FB-

High impedance feedback terminals. The feedback terminals have a very similar equivalent circuit as the

input terminals. The negative feedback (FB-) pin connects to an external resistive network to set the gain of

the in-amp. The positive feedback (FB+) pin can be used to shift the DC level of the output or as an output

offset.

8FB+

7

VS+

Positive supply terminal.

4

VS-

Negative supply terminal.

6

VOUT

Output Voltage.
