conversion. This circuitry can be enabled or bypassed by means of register 0x01, bit 6. A '0' will

disable the anti-corona circuitry and bypass the signal, while a '1' will enable it.

Temperature Sensor

The image sensor includes a temperature sensor that will provide the silicon temperature over the

MISO line. To retrieve the temperature, the user must perform a read request over the SPI to the

every LVAL falling edge, and stored in the register to be read by the user.

The formula to retrieve the temperature from the read digital values (in decimal) is the following:

Equation 14:

�� =

(�� ) − 50.74

1.42

℃

The digital step is approximately 0.7ºC.

The following table presents typical output values for the respective die temperature.

Attention

Please note that the temperature sensor is not a main feature of 4LS. It only monitors the silicon

temperature and does not have any influence in data stability and/or image quality. This

temperature sensor is only providing an indicative temperature value. This functionality is not part of

the core of this product.
