资 源 简 介

The ACF2101 is a dual, switched integrator that is typicallyused to convert a positive input current to a negative outputvoltage by integration, using an integration capacitor (CINT),either on the chip or a external capacitor provided by the user.Typical applications for the ACF2101 are photo diode integrators(as shown in Figure 1), current measurements, chargemeasurements, and a CT scanner front end. In Figure 1, 1/2 ofthe ACF2101 integrates a positive input current to a 0 to –10Voutput signal. The transfer function of the integrator is:
