Analogue / Linear / Mixed Signal ICs

E-peas has created an energy harvesting IC specifically for hand-held remote controls and wireless keyboards equipped with small solar cells. A cold start is possible from an input voltage as low as 275mV if 5µW of power is available. There are two versions, which optimise loading of the photovoltaic source in two different ways to get the best out of ...

STMicroelectronics has introduced a precision digital current, voltage and power monitor with a an I3C bus interface. Called TSC1641, it has two 16bit ΣΔ converters at its inputs, allowing simultaneous measurement of current (LSB=2.5µV) and voltage (LSB=2mV). The measured voltage can be anywhere from 0 to 60V (65V abs max), and the two current terminals sense with either polarity across ...

The building sector needs to modernise the communications infrastructure to meet net zero CO2 emission goals, urges Meghan Kaiserman. A fundamental factor in reaching net zero is the reduction of CO2 emissions across all industries. According to the International Energy Association (IEA), the building sector is not on track to meet global 2050 net zero CO2 emission goals, specifically the ...

Diodes has released a 2.5Gbit/s MIPI D-PHY 1.2 compliant signal repeater for high pixel-count cameras. PI2MEQX2503 regenerates and equalises two data lanes and a single clock. It “compensates for PCB, connector, cable and switching-related losses”, said the company, and “enables optimum electrical performance from a CSI2 source to a DSI sink”. Active, it consumes 120mW, then it has 5 and ...

ST has created a dual precision op-amp for automotive sensor signal conditioning, with 20µV input offset voltage and 100nV/°C drift, and operation over 4 to 36V and -40 to 125°C. Input common mode range for TSB182, as it will be known, is from its negative rail to within 2V of its positive rail, and the output is rail-to-rail. Maximum offset ...

STMicroelectronics has combined two LDOs, a CAN FD transceiver, four PWM-able high-side switches, a watchdog timer and a LIN transceiver into a single automotive-grade power IC. Called SPSB081, its aim is to provide a companion microcontroller with power, two serial interface transceivers, battery-voltage high-side load drivers and power for its peripherals. There are four devices giving 5V or 3.3V from ...

Texas Instruments has announced a 220V (or ±110V) analogue switch with 16 channel of single-throw switching. It has logic-level (1.8 to 5V) control inputs, with thresholds set by the separate 1.7 to 5.5V logic supply, and needs at least 40V across its switch supply pins (0V and +40V, or ±20V, for example) to operate. Absolute max for the controlled signal ...

SiTime has used MEMS instead of quartz crystals to make an oven-controlled oscillator with ±1ppb frequency stability and ±0.02ppb/°C frequency slope – all on a 9 x 7 footprint, including the oven. “No further thermal precautions are needed, additional covers are not needed,” the company told Electronics Weekly. “The physical footprint is 9 x 7 x 3.73mm, and the device ...

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 ...
