摘要：
本发明提供电路装置、振荡器、电子设备和移动体，能够抑制由于温度检测数据的急剧变化导致的不良情况，高效地实现A/D转换。电路装置包含：D/A转换器；比较部，其进行来自温度传感器部的温度检测电压与来自D/A转换器的D/A转换电压之间的比较；以及处理部，其根据基于比较部的比较结果的判定处理，求出作为温度检测电压的A/D转换结果的温度检测数据，处理部确定温度检测数据，以使接下来的第2输出时刻的温度检测数据相对于第1输出时刻的温度检测数据的变化为k×LSB以下。
摘要（英）：

A circuit device includes a D/A converter, a comparator that compares a temperature detection voltage from a temperature sensor unit with a D/A conversion voltage from the D/A converter, and a processing circuit that executes a determination process based on a comparison result from the comparator, and obtains temperature detection data as a result of A/D conversion of the temperature detection voltage, in which, the processing circuit determines the temperature detection data so that a change in the temperature detection data at a second output timing following a first output timing with respect to the temperature detection data at the first output timing is equal to or less than k*LSB.
