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 common-mode noise or DC offset.

Features

• Fully differential inputs and feedback

— Differential input range of ±2V

— Common-mode range of ±12V

— High CMRR at 4 MHz of 70 dB

— Stable at gains of 1, 2

• Calibrated and clean input clipping

• 4430—80 MHz @ G = 1

• 4431—160 MHz GBWP

• 380V/ms slew rate

• 0.02 or ° differential gain or phase

• Operates on ±5 to ±15V supplies with no AC degradation

Applications

• Line receivers

• ‘‘Loop-through’’ interface

• Level translation

• Magnetic head pre-amplification

• Differential-to-single-ended conversion
