Analogue / Linear / Mixed Signal ICs

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 ...

Nexperia has managed to achieve 100fF load capacitance in devices designed to protect USB4 signal lines. “Of special interest to engineers designing USB4 and Thunderbolt interfaces, the new device uses Nexperia’s TrEOS ESD protection technology with active silicon-controlled rectification,” according to the firm. “It delivers a combination capacitance down to 0.1pF), dynamic resistance down to 0.1Ω and 20A 8/20µs surge robustness.” ...

STMicroelectronics has tied up with Japanese audio company Alps Alpine to create an automotive class-D audio amplifier IC. Called FDA901, “the chip aims to contribute to the creation of multi-function, high-fidelity car audio systems that fuse the high efficiency of class-D amplifiers with the high-quality sound of ST’s class-AB amplifiers”, according to ST. According to ST it features low residual noise, ...

Maxim launched two LiDAR ICs at Embedded World this year, the Max400026 comparator and Max40660/Max40661 transimpedance amplifiers. The manufacturer is claiming these ICs represent a twofold increase of bandwidth and, at 128, an additional 32 channels over the nearest competitor in the same size module. The Max40026 is provided in a TDFN package size of 4mm2 while the 40660/1 come ...

New York-based fabless chip firm Ferric has teamed up with TSMC to put magnetic components on the metal layers of integrated circuits. The first product of the collaboration, Fe1038D, has a 2.0 x 3.2mm flip-chip die (<400μm thick) that includes all magnetics and passives needed to deliver 3A at between 0.6V and 1.5V from 1.8V-2.5V, with efficiency peaking above >85%. These chips can ...

Diodes has announced the PI3EQX12904A, a PCIe 3.0 and SATA3 re-driver with linear equalisation that supports PCIe 3.0 up to 8Gbit/s and SATA3 up to 6Gbit/s. It features four 100Ω differential current-mode logic (CML) data signals and is transparent to link training. To reducing inter-symbol interference, receiver equalisation is pin-adjustable, as is output linear swing (to 1Vmax) and flat gain. ...

Microchip has announced what it claims is industry first space-qualified Ethernet transceiver – a radiation-tolerant device based on a COTS (commercial off-the-shelf) chip. Called VSC8541RT, according to Microchip it is a single-port Gigabit Ethernet copper PHY with GMII, RGMII, MII and RMII interfaces. Radiation performances is: latch-up-immune to 78Mev and TID tested up to 100Krad. A second version,VSC8540RT, it bit-rate limited ...

CML Microcircuits has introduced an evaluation board for its low-power voice codec based around a  Raspberry Pi. The codec, the CMX655D, has been built into the EV6550DHAT – a board compliant with Raspberry Pi’s HAT (hardware attached on top) extension board standard. “The Raspberry Pi single board computer is widely recognised by makers, enthusiasts and professional developers as the platform of ...
