Analog-to-digital converter circuit for e.g. three-dimensional time-of-flight camera system, has evaluation unit that is configured such that error response is initiated if digital constant voltage lies outside tolerance voltage range

摘要

The analog-to-digital (AD) converter circuit has AD converter (110) comprising analog input (111) connected with constant voltage (UCON) of constant voltage source (200). The digital value of detected constant voltage is conducted to evaluation unit (100). The evaluation unit is configured such that an error response is initiated if the digital constant voltage lies outside a tolerance voltage range.
