Analogue / Linear / Mixed Signal ICs

Rohm is aiming at industrial and consumer applications with a ‘zero-drift’ operational amplifier which scores 9µV and 50nV/°C for its input offset – both maximum figures, which are typically 1µV and 15nV/°C. A first for the company, LMR1002F-LB, as it will be called, has a chopper architecture. Input current is typically 150pA (25°C) with 10pA offset. Both inputs and output are ...

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’). ...

This chipset provides new levels of connectivity with the world’s first commercially available devices using 3GPP NTN technology. It allows the use of satellite networks for reliable communication in remote locations, bringing connectivity to previously inaccessible areas, for use in agriculture, forestry and logistics. Judges were impressed with the evidence of its impact with one describing it as an “impressive ...

Microchip has announced 10 automotive-grade multi-channel temperature monitoring ICs that use external diodes, transistors or substrate diodes (MCU or other die) as sensors. Called the MCP998x family, they communicate over a serial bus and a pair of discrete output pins. Accuracy is ±1°C max (±0.2°C typ) with the IC and probe diodes anywhere in the range +20°C to +85°C – ...

Allegro MicroSystems has created an isolated gate driver IC for GaN power transistors that has no need for high-side bootstrapping nor the provision of a secondary side drive supply voltage. Instead, a dc-dc converter within AHV85111 produces secondary-side dc power rails – one positive and one negative – to provide gate drive power from a 12V supply (10.8 – 13.2V) ...

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 ...
