... Circuit Description: The heart of the NTE2054 is the V/I converter and reference–current generator. The V/I converter converts the input voltage applied between Pin10 and Pin11 to a current that charges the integrating capacitor on Pin12 for a predetermined time interval. At the end of the charging interval, the V/I con- verter is disconnected from the integrated capacitor, and a band– ...

... Pin6 provides a low–speed (4Hz) sampling rate. When Pin6 is fixed at +1.2V (by placing a 12k resistor between Pin6 and the +5V supply) a “hold” feature is available. While the NTE2054 is in the hold mode, sampling continues at 4Hz but the display data are latched to the last reading prior to the ap- plication of the 1 ...
