Analogue / Linear / Mixed Signal ICs

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it can reject PWM slew rates of >500V/µs and settles within 500ns to provide a 0.3% accurate (of full-scale) measurement of winding current “allowing motor control designers to increase drive frequency ...

TI has introduced an automotive system basis chip which integrates a controller and transceiver for Controller Area Network with Flexible Data Rate (CAN FD). Designed to meet the high-bandwidth and data-rate flexibility needs of in-vehicle networks, the TCAN4550-Q1 uses the Serial Peripheral Interface (SPI) bus of almost any microcontroller to implement, with minimal hardware changes, a CAN FD interface or ...

Believed to be one of the first devices to support Bluetooth Core 5.1, Nordic Semiconductor’s nRF52811 SoC is now available from Rutronik UK The Bluetooth Core 5.1 specification was introduced early this year and adds tracking and location functions. The nRF52811 is a multi-protocol SoC that supports IEEE 802.15.4 for Thread and ZigBee and also Bluetooth Direction Finding and Bluetooth Long Range for direction ...

Texas Instruments has revealed the fastest 12bit ADC – the ADC12DJ5200RF – that can sample two channels at 5.2Gsample/s, that can be interleaved into a single 10.4Gsample/s channel. That is two channels of 12bit 2.6GHz instantaneous bandwidth, or one of 5.2GHz instantaneous bandwidth. “The design comes from our centre in Friesing Germany – they have been designing high-speed ADCs there for ...

Cissoid has announced an adjustable linear regulator and logic gates that operate with junction temperature from -55°C up to 175°C – exceeding AEC-Q100 Grade 0 standard, the Belgian high-rel chip maker pointed out. Members of the firm’s new CXT series of automotive grade components, all with the same temperature range, the first is CXT-STA4919, a 50mA adjustable linear voltage regulator that can create ...

Power Integrations has launched a suite of offline switcher ICs incorporating 900 V primary mosfets. The devices include ICs for high-efficiency isolated fly-back power supplies and for simple non-isolated buck converters. See our full PCIM 2019 news roundup » Applications include three-phase industrial power supplies up to 480Vac, and high-quality consumer products destined for regions with unstable mains grids, tropical ...

Rohm addresses NXP's i.MX 8M mini application processors

For long data cables, Diodes has introduced aPCIe 4.0 compliant equalising repeater for use between 2.5Gbit/s and 16Gbit/s. Called PI3EQX16904GL, and branded a ReDriver by the firm, the device supports four 100Ω differential current mode logic (CML) data I/Os, providing programmable linear equalisation, output swing, and gain to reduce inter-symbol interference over a variety of physical media. “It is the industry’s ...

Analog Devices has released a couple of dual high-resolution SAR (successive-approximation register) ADCs operating at up to 4Msample/s, both packaged in 3 x 3mm 16pin LFCSP. 16bit AD7380 14bit AD7381 Dual simultaneous-sampling is available, and the firm is promoting them for motor control, sonar, power quality and data acquisition applications. “The conversion process and data acquisition use standard control inputs ...

Intended to fit inside the end of industrial data cables, Maxim has unveiled a dual IO-Link transceiver that includes a dc-dc converter and surge – claiming it to be both the smallest and most power-efficient available. Called MAX2251, the buck regulator supplies up to 300mA of load current and has an adjustable output from 2.5V to 12V). Switching is a ...
