8. APPLIED-CIRCUIT EXAMPLES
(7) Example of changing the temperature gradient with an external temperature sensor (thermistor)
to select three types of temperature gradients (-0.05%/°C, -0.3%/°C, and -0.5%/°C as V
other temperature gradient is required, as shown in Fig.8.13, connect a thermistor to resistor R
voltage adjustment) in series; you can change the temperature gradient to any value.
gradient than the one to be changed from Table 5.1.

The S1F76610, which is equipped with the temperature gradient selection circuit in the stabilizer, enables you
For a connection other than pins 10, 11, and 16, follow Fig.8.2. For pins 6 and 7, select a lower temperature
Note 1) The relation between RT and V
Note 2) The temperature characteristics of the thermistor indicate the nonlinearity; however, connecting
