| 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. |
