摘要： Method and apparatus for combining outputs of multiple DACs for increased bit resolution. A method for providing an increased bit resolution to a data converter operable to convert digital information to analog values. A first current Digital-to-Analog (IDAC) converter is controlled to provide current to a first output node, the first IDAC having a first current step size associated with the Least Significant Bit (LSB) thereof. A second IDAC is controlled to provide current to the first output node, the second IDAC having a second current step size associated with the LSB thereof that is smaller than the first current step size. The combination of the first and second IDACs increases the bit resolution of the first IDAC when driving the first output node with the second IDAC.

摘要： The integrated system on a chip with LINBUS network communication capabilities includes processing circuitry for performing predefined digital processing functionalities on the chip. A free running clock circuit generates a temperature compensated clock that does not require a synch signal from external to the chip. A LINBUS network communications interface digitally communicates with off-chip LINBUS devices. Communication between said on-chip LINBUS communications interface and the off-chip LINBUS devices is affected without clock recovery. The LINBUS network communication interface has a time base derived from the temperature compensated clock which is independent of any timing information in the input data received during a receive operation. The temperature compensated clock further provides an on-chip time reference for both the processing circuitry and the LINBUS network communications interface.

摘要： SAR analog-to-digital converter with abort function. A method for increasing the throughput of a data converter decision is disclosed. First, a data conversion operation is initiated to convert analog signals on an analog input on a data converter to digital data by sampling the analog signals on the analog signal input and then converting the sampled analog signals to digital data with a predetermined data conversion algorithm in a data conversion operation. The digital output of the data converter is compared to a threshold voltage value. When the output of the data converter is determined by the step of comparing to meet a predetermined relationship relative to the threshold voltage, the data conversion operation is terminated prior to the complete execution of the data conversion operation on the sampled analog signals.

摘要： A capacitive touch sensor circuitry comprises an interface for interconnecting with a plurality of I/O pins that connect to rows and columns of a capacitive sensor array. Monitoring circuitry, responsive to inputs from the plurality of I/O pins, determines when a capacitive switch in the capacitive sensor array has been actuated and stores an indication of the actuation of the capacitive switch. The monitoring circuitry then generates an interrupt responsive to the determined actuation. A control engine controls a manner in which the monitoring circuitry monitors the plurality of I/O pins. The control engine and the monitoring circuitry may be configured to monitor the plurality of I/O pins in a plurality of operating modes.
