Abstract: The present invention relates to circuitry comprising: interpolation filter circuitry configured to receive a digital input signal and to output an interpolated digital signal; amplifier circuitry configured to generate an output signal based on the interpolated digital signal; and protection circuitry. The protection circuitry is configured to activate in response to detection of a fault condition at an output of the amplifier circuitry. The circuitry further comprises first detection circuitry configured to output a control signal to disable the protection circuitry on detection of a transient signal at an output of the interpolation filter circuitry that is unrelated to a fault.

Abstract: An integrated circuit comprises first and second interfaces, an internal addressable space comprising a plurality of address ranges, and a control unit. Each of the first and second interfaces is coupled to the internal addressable space via the control unit. The control unit is configurable in a first state in which the control unit is configured to allow or deny the second interface access to a subset of the plurality of address ranges of the internal addressable space.

Abstract: In an example, an audio system, which may comprise an integrated circuit, comprises an amplifier and a combiner. The amplifier is configured to output a first amplified audio signal to a speaker. The combiner is configured to: receive the first amplified audio signal from the amplifier, receive a second audio signal, combine the first amplified audio signal and second audio signal into a combined signal, and output the combined signal.

Abstract: An apparatus for providing an output signal to an audio transducer comprises: one or more signal paths for receiving respective digital audio input signals, applying respective digital gains, and outputting respective amplified digital audio input signals; one or more inputs for receiving one or more volume parameters associated with the digital audio input signals; converter circuitry, coupled to the one or more signal paths, for converting the one or more amplified digital audio input signals into the analogue domain, and outputting an analogue audio input signal; an analogue gain element, for applying an analogue gain to the analogue audio input signal and outputting the output signal; and a control circuit, coupled to the one or more signal paths, operative to select the analogue gain based on a comparison of the volume parameters and the one or more digital audio input signals as multiplied by the volume parameters, and to select the respective digital gains for each digital audio input signal so that an overall gain in the respective signal path corresponds to a volume parameter associated with the respective digital audio input signal.
