TEMPERATURE MEASUREMENT SYSTEM The ADM1062 contains an on-chip, band gap temperature sensor whose output is digitized by the on-chip, 12-bit ADC. Theoretically, the temperature sensor and the ADC can measure temperatures from −128°C to +128°C with a resolution of 0.125°C. ...
Page 24
ADM1062 To measure ΔV , the sensor is switched between operating BE 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 ...
