Analogue / Linear / Mixed Signal ICs

Astute Group has signed a distribution agreement with Silanna Semiconductor to distribute its Plural ADCs in Europe and India. According to Astute, Plural ADCs offer a more affordable and versatile option with shorter lead times compared to current market alternatives. They are factory-configurable, providing over 150 ADC variants with sample rates ranging from 20 to 250Msps. The ADCs are available ...

Rohm has created a set of six current sense amplifiers with AEC-Q100 qualification for automotive use. They work with external shunt resistors, and there are two basic types: one (BD1423xFVJ-C) that can sense across the common-mode range of -14 to +80V and runs from 2.7 to 18V, and the other (BD1422xG-C) that can sense across -14 to +40V and runs ...

STMicroelectronics has made an eight-channel low-side driver for vehicles with extra functional safety hardware that “eases system-level ISO 26262 certification up to ASIL-B”, said the company. The nominal ratings of L9800, as it will be known, are: 12V power rail and 260mA per output. L9800 outputs can drive resistive, capacitive or inductive loads like relays, solenoids and LEDs,” said ST. ...

Diodes has introduced a 64Gtransfer/s PAM-4 intra-equipment range extender for PCIe 6.0 data busses, that is backwards-compatible with PCIe 5.0, 4.0 and 3.0. PI3EQX64904 is a four-differential-channel linear device with equalisation including tunable low and high-frequency and high-frequency zeros. “It optimises performance over a variety of physical media by reducing inter-symbol interference, correcting for known channel losses at the transmitter ...

Torex Semiconductor has created a nano-power dc-dc converter that can occupy only 7.7 x 3.1mm with all external capacitors – the necessary inductor is inside the device package. Called XCL108 and drawing 400nA quiescent current, it is a boost converter that will operate from inputs between 650mV and 5.5V – starting from anything above 1.6V. The device is a series, ...

Silanna Semiconductor has created a laser driver IC that can squeeze a 400W quad EEL (edge-emitting laser) module into 80mm2. SL2001 comes in a 14ball 1 x 3.5mm WLCSP (wafer-level chip-scale package) includes both a capacitor charging circuit and another block to dump that stored energy into the laser diode. Operating from a power source between 3 and 24V it ...

Analog Devices has created a fast power op-amp that can handle ±55V rails and ±1A outputs, with a digital control bus for setting internal parameters. Called ADHV4710, the output can swing ±52V with ±100mA loading, and its rails can vary down to ±12V. Despite being able to drive ±1300V/μs into 1nF, it is a voltage feedback amplifier, that can handle ...

At PCIM in Nuremberg this week, Texas Instruments announced an automotive-qualified LLC controller for light electric vehicle charging, and demonstrated it in a three-stage ac-dc battery charger for electric two-wheelers. (LLC is an inductor-inductor-capacitor topology, see diagram) “But despite the benefits that the LLC topology can offer, including minimal standby power and low audible noise, electric vehicle manufacturers have been ...

Navitas Semiconductor is aiming at motors up to 600W with a GaN motor drive IC. “Specifically designed for motor drive applications, this integrated solution combines two GaN FETs in a half-bridge configuration with drive, control, sensing and autonomous protection,” according to the company. Called NV6288, it is a 650V part with two 120mΩ GaN HEMTs in an 8 x 10mm ...

Advanced Linear Devices has introduced a voltage balancing IC for series-connected pairs of 3.3V supercapacitors. Inside is a pair of mosfet-like devices with a sharp ‘knee’ in their voltage-current characteristic. As such, they are not literally balancing, but are clamping against over-voltage and passing spare current to the other cell. Called ALD910030, “this dual mosfet provides auto-balancing capabilities and power ...
