Fig. 13-6 This circuit converts temperature (from 0 to 128°F) to a serial data word (8 bits when appropriate clock and enable signals are received from the system). The scales are adjusted by the 10-kΩ pot so that all 8 bits are at digital 1 when the temperature is + 128°F, In practice, the VREF pin of the LM385 is set to 1.28 V.
