Operational amplifier chip capable of automatically measuring and controlling temperature

Abstract

The invention discloses an operational amplifier chip capable of automatically measuring and controlling temperature. The operational amplifier chip comprises an upper heat dissipation plate, a packaging chip and a lower supporting assembly; the packaging chip comprises an upper cover plate and a lower protection frame; an inner cavity of the lower protection frame is filled with a packaging body;the inner cavity of the packaging body is connected with a chip body in a glued mode; the surface of the chip body is connected with heat conduction paste in a glued mode; the surface of the heat conduction paste is attached to the bottom of the upper cover plate; and a heat conduction groove is formed in the surface of the upper cover plate. The invention relates to the technical field of operational amplifier chips. When the operational amplifier chip capable of automatically measuring and controlling temperature is used, the packaged chip is supported through the lower supporting assembly,the packaged chip is prevented from making direct contact with a PCB, heat input is effectively isolated; heat generated when the chip works is transmitted out through contact between the upper heatdissipation plate and the upper cover plate, the heat is effectively dissipated; heat input is prevented from occurring at the bottom; and the heat is dissipated from the top, so that the over-high temperature of the packaged chip can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of operational amplifier chips, in particular to an operational amplifier chip for temperature self-measurement and control. Background technique [0002] An operational amplifier ("op amp" for short) is a circuit unit with a very high amplification factor. In actual circuits, some kind of functional module is usually combined with a feedback network. It is an amplifier with a special coupling circuit and feedback. Its output signal can be the result of mathematical operations such as addition, subtraction, or differentiation and integration of the input signal. Because it was used in analog computers in the early days to realize mathematical operations, it was named "operational amplifier". An operational amplifier is a circuit unit named from a functional point of view, which can be realized by a discrete device or in a semiconductor chip. With the development of semiconductor technology, most operatio...
