Analogue / Linear / Mixed Signal ICs

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 ...

Toshiba has announced an IGBT/mosfet gate driver equipped with additional built-in functionality. The TLP5231 is aimed at applications including industrial inverters, uninterruptible power supplies (UPS), power conditioners for solar energy and motor controls. The pre-driver has a pair of outputs designed to drive external p-channel and n-channel mosfets used for current buffers. This allows the usage of mosfets with various ...

Power Integrations has announced an expansion of its Innoswitch families of offline CV/CC flyback switcher ICs. The Inn3x78C devices incorporate a smaller “size 8” 750V PowiGaN transistor, enabling power supplies that deliver between 27W and 55W without heatsinks. The ICs are housed in the same InSOP-24D package as larger members of the GaN-based Innoswitch 3 families, which target up to ...

Renesas has introduced a mmWave synthesiser for 5G and broadband wireless applications. “We developed our 8V97003 for mmWave radios, ensuring it meets demanding frequency range, phase noise, and output power requirements,” said Renesas v-p of timing products Bobby Matinpour. “8V97003 is particularly well-suited for emerging applications above the 6GHz carrier frequency, including broadband wireless, microwave back-haul, and 5G radios.” The ...
