ABSTRACT:
The invention relates to a method, mixed signal integrated circuit, mobile communication device, system and computer program for controlling an analog-to-digital converter. To reduce latency and power consumption when accessing conversion results from analog signals the invention provides a method for controlling an analog-to-digital converter with transmitting control signals and data between the analog-to-digital converter and a digital circuit using a serial interface generating a read command within the digital circuit transmitting the read command from the digital circuit to the analog-to-digital converter via the serial interface receiving the read command in the analog-to-digital converter converting an analog signal from an input terminal of the analog-to-digital converter into a digital signal within the analog-to-digital converter providing the digital signal immediately after conversion to the serial interface and receiving the digital signal within the digital circuit via the serial interface immediately after the read command.
