2 Temperature Monitor

TAS2110, TAS2562, TAS2563 and TAS2564 have an internal die temperature sensor that has a measurement range from -40°C to 150°C and a resolution of 8 bits. This sensor is always enabled in order to keep the device within safe operating limits.

If needed, the value of this temperature monitor can be read from register 0x2C on page 0x00; further details on how to obtain the actual temperature value are available in the SAR ADC section of each device data sheet.
