Publication number: 20250233944Abstract: 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.Type: ApplicationFiled: April 4, 2025Publication date: July 17, 2025Applicant: Cirrus Logic International Semiconductor Ltd.Inventors: Robert D. RAND, Jon E. EKLUND, Pradeep SAMINATHAN, Peter HORSFALL

Patent number: 12039090Abstract: 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.Type: GrantFiled: August 4, 2021Date of Patent: July 16, 2024Assignee: Cirrus Logic Inc.Inventors: Michael Chandler-Page, Pradeep Saminathan, Jon Eklund, Neil Whyte, José Arnaldo Bianco Filho, Abhinav Sharma

Patent number: 11843354Abstract: 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.Type: GrantFiled: June 14, 2021Date of Patent: December 12, 2023Assignee: Cirrus Logic Inc.Inventors: Pradeep Saminathan, Graeme S. Angus, John B. Bowlerwell
