    Abstract: A device includes a memory, at least two input/output (IO) pins, and slave identifier (ID) selection circuitry. The memory stores a slave ID, which identifies the device to other devices in a serial communication process. The slave ID selection circuitry changes the stored slave ID based on which one of the IO pins is coupled to a supply voltage. By changing the slave ID of the device based on which one of the IO pins is coupled to a supply voltage, a number of devices with otherwise identical slave IDs may change their slave IDs in order to participate in a serial communication process on the same bus. Further, the slave ID of the device may be changed without using an additional IO pin on the device.

    Abstract: Analog-to-digital pulse width modulation circuitry includes thermometer code generator circuitry, clock generator circuitry, delay selection circuitry, and an output stage. The thermometer code generator circuitry is adapted to generate a digital thermometer code based upon a received analog input voltage. The clock generator circuitry is adapted to generate a reference clock and a plurality of delayed clock signals. The delay selection circuitry is connected between the thermometer code generator circuitry and the clock generator circuitry, and is adapted to select one of the delayed clock signals to present to the output stage based upon the generated thermometer code. The selected delayed clock signal is delayed by an amount of time that is proportional to the generated thermometer code. The reference clock signal and the selected delayed clock signal are delivered to the output stage where they are used to generate a pulse width modulated output signal.
