14 | ----------- | ||
15 | |||
16 | The LM77 implements one temperature sensor. The temperature | ||
17 | sensor incorporates a band-gap type temperature sensor, | ||
18 | 10-bit ADC, and a digital comparator with user-programmable upper | ||
19 | and lower limit values. | ||
20 | |||
21 | Limits can be set through the Overtemperature Shutdown register and | ||
22 | Hysteresis register. | ||
