Analog Devices announced three enhanced Automotive Audio Bus (A2B) transceivers with the capability to tailor system-level performance to stringent electromagnetic compatibility (EMC) requirements.

The AD242x series of transceivers also allow expanded use cases for microphone connectivity and reduce cabling complexity by distributing audio and control data , plus clock and power, over a single, unshielded twisted-pair wire.

Maxim Step-Down Switching Converters

Maxim released EMI-compliant Himalaya step-down switching converters and power modules designed to speed time to market and reduce design cycles. These devices, which comply with CISPR 22 and EN 55022, are suited for general-purpose applications, including industrial, building automation, factory automation and consumer electronics.

Electromagnetic interference (EMI) compliance is a mandatory, critical design challenge for end equipment manufacturers. Device makers often fail EMI compliance after a design is completed because of the power supply IC, sub-optimal layout, filtering techniques and component selection. Maxim hopes its converters will help solve that design hurdle.

Additional technical specifications are available on Maxim’s website.

RS Components DC/DC Converters for Medical Devices

RS Components introduced the TIM 2 and TIM 3.5 series of DC/DC converters. The converters provide reinforced isolation of up to 5000V AC (RMS), which is important for medical applications. Also, providing a low leakage current of less than 2μA, the converters are suited for use in insulating electrical equipment within the BF classification for patient applied parts.

The converters are approved to IEC/EN/ES60601-1 3rd edition for 250V AC 2xMOPP up to an altitude of 5000m and an ISO14971 risk management file is available. Further approvals include compliance with the latest EMC requirements IEC 60601-1-2 4th edition for medical equipment.

Synopsys stated that Samsung has certified the Synopsys Custom Design Platform for its Foundry’s 7-nanometer (nm) Low Power Plus (LPP) process. 7LPP is Samsung’s first semiconductor process technology to use extreme ultraviolet (EUV) lithography, a process that reduces complexity and offers better yield and turnaround time when compared to its 10-nanometer (10nm) FinFET predecessors.

Synopsys custom design tools have been updated to support Samsung Foundry’s 7LPP requirements. In addition, a Synopsys-ready process design kit (PDK) and custom design reference flow are available from Samsung Foundry.

Texas Instruments (TI) released three amplifiers that emphasize speed and precision, allowing designers to create more accurate circuits for error-sensitive applications. The devices support precise measurement and faster processing of various input signals in test and measurement, medical and data-acquisition systems.

Key features of the amplifiers are as follows:

  • OPA2810: 27-V junction gate field-effect transistor (JFET)-input dual operational amplifier (op amp), 120-MHz bandwidth, 500-µV max offset voltage.
  • OPA189: 36-V zero-drift op amp, 14-MHz bandwidth, multiplexer (MUX) friendly.
  • THS3491: 32-V current-feedback amplifier, 900-MHz small-signal bandwidth, ±420-mA output current.

Information concerning pricing and availability can be found on TI’s website.
