PSØ8 offers an internal low noise com- parator. Alternatively, an external comparator might be used. 3.5.7.1 Internal Comparator The internal comparator is selected by setting reg11, sel_compint = 1. By means of the internal comparator it is possible to get about 60,000 divisions peak-peak at 2 mV/V, 5 Hz update rate and MEDIAN 5 software filter. Figure 3.23 Internal comparator 3.5.7.2 External Comparator The precision of the measurement can be improved by using an external bipolar comparator. With an external bipolar comparator it is possible to get up to 150k divisions at 5Hz update rate. Figure 3.24 External comparator Recommendations: Low-noise PNP transistors like 2N5087 / CMKT5087 or BC859 should be used. 5 transistors in parallel should be connected at the LOAD side. It is not necessary to have matched transistors. Use a COG-type capacitor for the low-pass filter capacitance. Member of the ams Group |
