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.
