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
The amplifiers have an operational temperature of
b
40 C to
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
