The device has been primarily developed for car radio applications where long connections between signal sources and amplifiers (or boosters) are necessary and where ground noise has to be eliminated. The device is intended to be used to receive line inputs in audio applications that require a high level of common-mode rejection. The device is contained in an 8-pin small outline (SO) or dual in-line (DIP) package. MAX. 18 14 +0...
