General Description

The EL4430 and 4431 are video instrumentation amplifiers

which are ideal for line receivers differential-to-single-ended

converters transducer interfacing and any situation where a

differential signal must be extracted from a background of com-

mon-mode noise or DC offset

These devices have two differential signal inputs and two differ-

ential feedback terminals The FB terminal connects to the am-

plifier output or a divided version of it to increase circuit gain

and the REF terminal is connected to the output ground or

offset reference

The EL4430 is compensated to be stable at a gain of 1 or more

and the EL4431 for a gain of 2 or more

a

85 C and are packaged in plastic 8-pin DIP and SO-8

The EL4430 and EL4431 are fabricated with Elantec’s proprie-

tary complementary bipolar process which gives excellent sig-

nal symmetry and is free from latchup
