A gain control arrangement for use in analog-to-digital conversion includes a current generator that generates gain currents as a function of externally applied resistances. The gain currents are sequentially provided to the analog-to-digital converter, enabling the converter to use a single set of externally applied resistances to set differentiated gain factors in each of its channels.

Arrangement and method for controlling gain of analog-to-digital

A circuit protection device designed to protect a pair of electrical circuits by fracturing at such time as an overcurrent condition has occurred in a first of the circuits, this novel device comprising a substantially flat substrate of non-conductive, frangible material upon which a resistive component and a fuse conductor reside in an adjacent relationship on a common surface. The resistive component is part of a first circuit, and the fuse conductor is part of a second circuit. The resistive component, at the time of an overcurrent therethrough, becomes hot and causes a heating of the near surface of the frangible substrate. The frangible substrate, as a result of the uneven heating of its opposite surfaces, elongating and then fracturing, the fracturing of the frangible substrate thereby bringing about a fracturing of the resistive component as well as a fracturing of the fuse conductor, thus to effect an interruption of the first circuit as well as a substantially simultaneous interruption of the second circuit. This novel device is admirably suited for protecting a subscriber line interface circuit.
