ADM1063
To measure ΔV
currents of I and N × I. The resulting waveform is passed through
a 65 kHz low-pass filter to remove noise and through a chopper-
stabilized amplifier that amplifies and rectifies the waveform
to produce a dc voltage proportional to ΔV
measured by the ADC to produce a temperature output in 12-bit
offset binary. To further reduce the effects of noise, digital
filtering is performed by averaging the results of 16 measurement
cycles. A remote temperature measurement takes nominally
600 ms. The results of remote temperature measurements are
stored in 12-bit, offset binary format, as shown in Table 10. This
format provides temperature readings with a resolution of 0.125°C.
