Abstract
The utility model relates to an integrated block for an analog quantity conversion circuit, and the integrated block comprises an upper cover and a base which is connected with the upper cover. The periphery of the base is provided with bonding pads. The interior of the upper cover is fixedly equipped with a substrate. One surface of the substrate is equipped with an IC chip and an electronic element, and the other surface of the substrate is equipped with a film formation resistor. The IC chip, the electronic element and the film formation resistor and the bonding pads are connected together through gold wires. The method of thick film integration is used in the utility model, and the analog quantity conversion and an acquisition circuit are integrated in a packaging structure, thereby reducing the occupied area. The conversion circuit carries out electric isolation for an analog voltage signal which is inputted externally, and the analog voltage signal is converted into a normalized voltage signal which is outputted through an internal one way selected from an eight-way analog switch. Therefore, the occupied area of the conversion and collection of multi-way analog signals is reduced.
Description
Technical field
The utility model relates to a kind of integrated package, is applicable to the Acquisition Circuit of multi-analog signal, particularly analog quantity translation circuit integrated package.
Background technology
When can not analog signals altogether being gathered for input and output signal, after needing to adopt discharge circuit to be isolated and it being transformed to normalized voltage signal, by analog switching circuit, switch and gathered.While can not analog signals altogether being gathered for many roads, will use a lot of discharge circuits and analog switching circuit, be to adopt amplifier IC device, analog switch device and resistance capacitance etc. to make printed board (PCB) is upper to the prior art of multichannel isolated variable signals collecting.Because the discrete component that adopts the outsourcing finished product is made in printed board, the area taken is larger, is unfavorable for, in limited space (particularly at space industry), a large amount of analog signalses is converted to collection.
The utility model content
Technical problem to be solved in the utility model is, reduces the area occupied that the conversion of multi-analog signal gathers, and can be useful in the conversion collection that multichannel analog signals is carried out in limited space.
For achieving the above object, the utility model is taked following technical scheme, analog quantity translation circuit integrated package, comprise upper cover and the base be connected with upper cover, the surrounding of base is provided with pad, in upper cover, substrate fixedly is housed, and the one side of substrate is equipped with IC chip and electronic component, another side is equipped with into film resistance, between IC chip, electronic component, one-tenth film resistance and pad, by spun gold, connects.
The utility model adopts the integrated method of thick film, the analog quantity conversion is integrated in encapsulating structure with Acquisition Circuit, thereby the area that reduces to take, the analog voltage signal of outside input is carried out to electricity through this circuit and isolate and be transformed into normalized voltage signal, reduce the area occupied that the conversion of multi-analog signal gathers.
