Video Instrumentation Amplifiers
The EL4430 and EL4431 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 common-mode noise or DC offset.
These devices have two differential signal inputs and two
differential feedback terminals. The FB terminal connects to
the amplifier 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 -40°C to
+85°C and are packaged in plastic 8-pin DIP and SO-8.
The EL4430 and EL4431 are fabricated with Elantec’s
proprietary complementary bipolar process which gives
excellent signal symmetry and is free from latchup.
