Analog Devices has created a pair of 22V stereo Class-D audio amplifier that idle at 6mA and shut-down to microamps. MAX98415A and MAX98425A are similar, and both including envelope tracking control that saves power by instructing an external dc-dc converter to provide the amplifiers main power input with just enough voltage for clean output signals. The difference between the two ...

Q.Ant will demonstrate of native analogue photonic processing at ISC 2025, the high-performance computing conference. “For the first time, attendees will be able to interact directly with functional photonic computing, witnessing how light can drive energy and computational efficiency for AI, physics simulations, and other complex scientific workloads”. according to the company. “Q.Ant is attacking two of the biggest challenges ...

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 ...

The latest episode of the Electronics Weekly podcast, CHIIPS, is out. Check out the latest interview with industry veteran Ash Madni.

Microchip is aiming at analogue sensors with a microcontroller that can measure signals while consuming less than 3µA while sleeping with one comparator monitoring an in-coming voltage. Called PIC16F17576, it has a power-saving ‘analogue peripheral manager’ (APM). “The APM controls which peripherals are active to minimise total energy consumption and enable battery-operated applications,” according to the company. Inside the APM ...

Microchip has added high-performance analogue blocks to its PIC32 MCUs: 12bit 40Msample/s ADCs, 5ns comparators and 100MHz GBW (gain.bandwidth) op-amps. There are implemented in in the new 32bit 200MHz PIC32A family. On top of the analogue blocks are hardware safety and security features such as ECC (error code correction) on flash and ram, built-in memory self-test, IO integrity monitoring, clock ...

iC-Haus has created a high-speed sine-to-digital signal conditioning interpolation IC for magnetic or optical position sensors. “Linear scales and angular sensors can benefit from higher resolution and accuracy, enabling an outstanding measurement precision, a faster motion speed or an improved control quality for drives,” claimed the company. By combining analogue and digital processing, the IC, called iC-NQE, takes in analogue ...

TDK has created a spin-memristor for analogue neural networks, and built a network that can separate three types of sound in real-time. It has been collaborating on memristors with French research lab CEA since 2020, and has now announced a collection of memristors packaged in an IC (described as ‘three elements by two sets’, photo). Semiconductor process behind this IC ...

Nisshinbo Micro Devices has released a series of industrial 5V analogue front end ICs with high-resolution ΣΔ converters, input multiplexers, programmable gain amplifiers and sensor excitation current sources. NA2202 has 16bit resolution NA2203 has 20bit resolution NA2204 has 24bit resolution “Microcontrollers with 5V operating voltage are still widely used in the industrial equipment market, according to the company. “In order ...

Nexperia has unveiled analogue switches that can work with control logic from 1.8 to 5V, regardless of supplies between 1.5 and 5.5V. There are two versions: NMUX1308, an 8:1 analogue multiplexer/demultiplexer which is compatible with, but more capable than, existing 4851 and 4051 analogue switches, and the NMUX1309 dual 4:1 analogue mux/demux which can replace 4852 and 4052 devices. All ...
