Startup Behaviour of Internal Temperature Sensor

I have a problem with the internal temperature sensor of the AD 9361. We use the sensor in continuous running mode. Before I read the sensor value out of the register, I stop the ADC, afterwards I start it again.

 

I have following problem now: after the reset of the AD 9361 chip, the temperature sensor delivers for circa 300 ms - 350 ms wrong values. The values are at about 2 times as big as the valid samples later.

 

Does the internal temperature sensor needs initial time, before the values are valid?
