Analogue / Linear / Mixed Signal ICs

Designed with a whisper-quiet noise floor – <30μV (130dB SNR), 1200AS is a family of high power Class-D audio amplifiers from ICEpower of Copenhagen. Intended for PA speakers, line arrays and professional single or dual sub-woofers, they are based on the firm’s own ICEedge chip-set and include a universal mains switch mode power supply with PFC – with ErP and ...

Allegro adds magneto-resistive sensors to its Hall-based range of current and magnetic field devices

Allegro MicroSystems announces current sensor ICs for AC or DC with 200kHz bandwidth and 2.5µs response time

Rohm has introduced ‘high-fidelity’ power supply ICs aimed at audio devices requiring high-resolution audio play-back. Above the quality of CD audio, it sees high-resolution audio sources typically playing back at “greater than 96kHz and 24bit”. Called the BD372xx series, the regulators have a newly-developed fast error amp circuit and low-noise architecture. “Multiple parameters that were shown to affect audio quality ...

To increase system-in-package integration density, Analog Devices is stacking die on a passives-on-silicon substrate using technology developed at its Limerick design centre. Dubbed iPassive, “this is a new thing in system-in-package”, ADI field application engineer Thomas Tzscheetzsch told Electronics Weekly at Embedded World in Nuremberg. “The passives are in the silicon, not in poly, real silicon. They are matched to ...

Silicon Labs revealed a Wi-Fi transceiver which consumes so little that it can be used in battery powered IoT sensor nodes, for example. Revealed at Embedded World, the WFM200 system-in-package (SiP, 6.5 x 6.5mm LGA52) consumes 200µA (average, delivery traffic indication message (DTIM)= 3). “We’ve delivered the first low-power Wi-Fi portfolio designed specifically for the IoT, enabling secure, battery-powered connected ...

Renesas is aiming at industrial controllers by building an entire Profinet interface inside an RJ45 connector. EtherCAT and EtherNet/IP versions will follow once associated software is ready. The hardware is accompanied by software to support the industrial Ethernet protocol stacks. Dubbed I-RJ45, there are single and dual port versions “which simplify integration for industrial Ethernet by supporting various industrial network ...

Microchip’s MCP6411 operational amplifier can operate with a single supply voltage as low as 1.7V, while drawing 55μA quiescent current (max). Called MCP6411, input offset is ±1.0mV max, and both input and output operate rail-to-rail. Compensation means it is unity gain stable, and it has a gain bandwidth product of 1 MHz (typ). “The MCP6411 has enhanced EMI protection to ...

Toshiba Electronics Europe has added a 45W (4Ω load) four-channel audio power amplifier to its in-car entertainment range. TCB001FNG is based upon a complementary MOS process with n and p-channel DMOS fets. Supply can vary across 6 to 18V, allowing operation while the engine is idling or cranking. “The product includes functions to detect and prevent abnormal noise with Toshiba’s ...

TI has introduced an op amp which, it claims, is the first to combine ultra-high precision with the industry’s lowest supply current. “With exceptional power-to-precision performance, the LPV821 zero-drift, nanopower op amp enables engineers to attain the highest DC precision, while consuming 60 percent less power than competitive zero-drift devices.,” says TI. The LPV821 is designed for use in precision ...
