Abstract: A sensor assembly including a transducer and interface circuit with a DSL-controlled input voltage is disclosed. The interface circuit includes a logic circuit configured to generate and provide a pulse width and amplitude modulated (PWAM) signal to an n-bit iDAC coupled to an analog front end (AFE) amplifier or buffer. The PWAM signal is based on an output of a forward signal-path ADC or low-power ADC coupled to the AFE amplifier or buffer, wherein the n-bit iDAC regulates a voltage at the input of the AFE amplifier or buffer based on the PWAM signal.
