Analogue / Linear / Mixed Signal ICs

Analog devices is aiming at industrial control with a four-channel I-O integrated circuit. Control is though a four-wire digital interface to a host controller that clocks at up to 24MHz and is compatible with SPI, QSPI, Microwire and other protocols. Each of the four channels on the other side of the chip can be software-configures as: Voltage input (0-10V, 200kΩ load ...

ADA4523-1 is a precision ‘zero-drift’ op-amp from Analog Devices that works across 4.5V to 36V, drawing 6mA worst case. The output is rail-to-rail, and the input includes the negative rail – working from 100mV below the negative rail to 1.5V below the positive rail. Maximum offset voltage is ±4µV and, due to self-calibrating circuitry, this drifts at only 0.01µV/°C (max ...

Diodes has announced what is says is industry’s first AEC-Q100 grade 3 qualified 10Gbit/s USB-C DisplayPort Alternate (DP-Alt) mode linear re-driver IC. DP-Alt mode allows the transfer of DisplayPort signals through a USB Type-C connector. Called PI3DPX1207Q, the Diodes’ chip supports 8.1Gbit/s DP1.4 and 10Gbit/s USB 3.2 specifications. It is a “transparent, protocol-agnostic re-driver capability for a range of automotive ...

Renesas’ ZSSC3240, announced earlier today, is a sensor signal conditioning chip that provides amplification and 24bit digitisation for bridge and half-bridge resistive sensors, followed by 26bit sensor-specific correction in a maths core that handles auto-zero, span, and 1st and 2nd order temperature compensation from coefficients stored in non-volatile memory. Support circuits to feed the sensor is included, and measurement is ratiometric ...

Renesas has brought out a sensor signal conditioner (SSC) – the ZSSC3240 – for sensor applications such as resistive pressure sensors and medical infrared thermometers features with up to 24 bits ADC resolution. With a flexible sensor front end and a broad range of output interfaces, the ZSSC3240 can be used for nearly all types of resistive and absolute voltage ...

STMicroelectronics has integrated common-mode filters and ESD suppression into automotive data line protectors. “These are the first common-mode filters on the market with automotive-grade qualification and automotive surge compliance guaranteed,” claimed ST. “They are not only produced and qualified according to AEC-Q101 requirements but are also designed and tested against automotive surge specifics such as ISO10605.” The products each protect ...

Melexis has launched the MLX91377 hall-effect sensor IC, designed for use in automotive applications such as electric power-assisted steering. With an operating temperature between -40℃  and 160℃, the firm says the device combines high linearity with excellent thermal stability, including low offset and sensitivity drift. It’s been developed as a safety element out of context (SEooC), and complies with the ...

Toshiba has launched two 80V N-channel power mosfets based on its U-MOSX-H process. The devices are said to be suited to power applications where low-loss operation is important, including ac-dc and dc-dc conversion in data centres and communication base stations as well as motor drive equipment.  Both the TPH2R408QM and TPN19008QM exhibit a reduction of around 40% in drain-source on-resistance ...

TDK has introduced the EZA2500W-32048 bi-directional dc-dc converter model to its EZA series, following the 11kW variant released last year. The high voltage range now covers 260-400Vdc and the lower voltage 36-65Vdc. The operating temperature is -10 to 50°C. Double sided protective board coating and long-life dust resistant fans have also been included. The output voltage and current can be ...

Samsung has announced two “all-in-one” PMICs, MUA01 and MUB01, specifically designed for today’s true wireless stereo (TWS) devices. Unlike wireless headphones, TWS earbuds have no wire that connects the two earpieces. The MUA01 and MUB01 PMICs have been designed for the charging case and the earbuds respectively. The devices reportedly integrate up to ten discrete components into one, including switching ...
