2MHz industrial isolated input ICs need only secondary-side power

Novosense NSI860x isolated input chips

Novosense Microelectronics has created a pair of isolated digital input chips suitable for 24V industrial control applications that only need power on the output side. 4-channel NSI8604 (SSOP16 package) and 8-channel NSI8608 (SSOP20) provide input/output isolation when converting voltages in the range of -60V to 60V to logic signals. (The third digit is a capital ‘i’, not a numerical ‘1’). ...

UL-approved 100Mbit/s digital isolators

Wurth digital isolators

Würth Elektronik has introduced two families of surface-mount multi-channel galvanic isolators for digital signals. Devices in the WPME-CDIP family have four 100Mbit/s isolated channels and a built-in dc-dc converter that provides isolated power from one side to the other. Different versions have different combinations of digital isolator directions: all from input to output, three in that direction and one returning, ...

TI takes the ‘opto’ out of opto-isolators with all-electronic replacement

TI opto-emulator

Texas Instruments has added an analogue version of the non-optical replacement for digital opto-isolators it just revealed. Called ‘opto-emulators’, both analogue and digital versions replace the LED and photo-diode or photo-transistor within a conventional opto-isolator with an SiO2 barrier across which the a modulated version of the input signal is passed – probably magnetically (Electronics Weekly has requested clarification). The ...

Tension and compression sensors with IO Link

HBK U9C force sensor with IO Link

HBK has added IO Link digital communication to a range of tension and compression force sensors. U9C sensors (pictured) measure tension and compression, and C9C sensors measure only compression. This article was republished with far more information here The sensors easing digital up-grades by having identical mechanical dimensions and threads to their analogue counterparts. “With a standardised interface to any ...

85V 75A 20bit current, voltage and power monitor has 535μΩ sense resistor

TI INA780x digital output current monitor

Texas Instruments has created a series of precision current monitors with digital outputs, for use across power rails from  -100mV to +85V, at up to ±78.64A. In each case, an internal ΣΔ ADC measures current across an integrated sensing resistor, as well as voltage and temperature – communication with the host if via I2C. The ICs need a separate supply ...

150Mbit/s four channel industrial digital isolators shun 5kV and 100kV/μs

Toshiba DCL541A01 B01 digital isolator

Toshiba has introduced a series of multi-channel digital signal isolators that “ensuring stable high-speed digital communications even in the toughest factory floor environments”, it claims. They have 100kV/μs minimum common-mode transient immunity (1.5kV common-mode, 25°C), and carry data rates up to 150Mbit/s. Isolation is 5kV for 1 minute. Called the DCL54xx01 series, they are four-channel devices with different combinations of ...

Books are analogue?

‘The Book: A cover-to-cover ex­plor­a­tion of the most power­ful ob­ject of our time’ is a charming and fascinating Radio 4 series that played over the weekend in omnibus form. I loved every minute of it, although was jarred by its final line, which described books as ‘unrepentingly analogue’. But surely, they are digital, as there are 26ish letters plus punctuation ...

ISSCC 2023: The processors that the IEEE wanted to hear about

ISSCC9.2 Syntiant detail

A recent innovation at ISSCC is for the organisers to hand-pick a few ICs that they would like to hear about the conference – all the other speakers have to apply to present their innovations. This year they picked machine learning accelerators for both training and inference, an ultra-high bandwidth chip-to-chip link and an ‘infrastructure processing unit’ (IPU) for off-loading ...

Digital isolator has two 100Mbit/s channels in the same direction

ST STISO620 isolated digital link

STMicroelectronics has created a fast dual-channel high-speed digital isolator with both channels in the same direction. Called STISO620, it s”6kV thick-oxide technology ensures robust galvanic isolation”, according to the company. “Built to maintain insulation integrity during system faults and with ageing, they enhance reliability in industrial and consumer applications.” Peak withstanding is 4kVpk, isolation is to 2.83kVrms, and maximum working is ...

Tektronix 500MHz scope is 38mm thick for field and bench

Tektronix 2_Series_MSO_Touchscreen

Tektronix has unveiled flat-profile 500MHz mixed-signal oscilloscopes intended to be used on the bench and in the field. Called ‘2 Series Mixed Signal Oscilloscope’, they maximise frontal area for display (10.1in touchscreen) and control by being only 38mm thick. Weight is 1.8kg and they “can go seamlessly from the bench to the field and back, enabling workflows previously unimagined on ...
