Analogue and Discretes

Japanese gallium oxide power device start-up Flosfia has raised Y750m (£5m) in series B funding. The firm, a spin-out from the Kyoto University, is aiming to commercialise crystalline α-Ga2O3 (corundum/sapphire/ruby structure) in power transistors and Schottky diodes – with the intention of manufacturing 600V TO-220 diodes in 2018 to compete against silicon carbide power devices. Its second intellectual property is ...

ON Semiconductor has picked up two consumer semiconductor awards in the run up to CES 2017 which takes place in Las Vegas next month. The Consumer Technology Association (CTA) recognised On Semiconductor’s Ezairo 7150 SL audio processor for hearing aids along with its Smart Passive Sensor (SPS). Ezairo 7150 SL is described as “an open-programmable digital signal processing (DSP)-based hybrid, which enables wireless connectivity in hearing aids ...

IQD’s new analogue ASIC-based temperature-compensated crystal oscillator (TCXO) is tested using one frequency reading every two degrees centigrade over the full operating temperature range. “This, combined with a high order compensation circuit, delivers a frequency stability as tight as ±0.5ppm over -40 to +85°C,” said the firm. Called IQXT-274, it comes in a 3.2 x 2.5 x 1.1mm hermetically sealed ...

Texas Instruments has introduced what it claims are the industry’s first precision nano-power op amps. LPV811 consumes 450nA (typ) and offers 370µV (max, +/-60μV typ) offset, while offset in the dual LPV812 is 300µV. If more offset can be tolerated, there are even lower current versions – see below. The op-amp family is aimed at battery-powered sensors in building automation, ...

E2V is claiming a world first with a DAC that can generate K-Band (18-27GHz) signals directly, without a mixer. Called EV12DS460, conversion is 12bit at at 6Gsample/s guaranteed, with operation possible up to 7Gsample/s. “Removing up-conversion stages in our customers’ systems operating up to K-band will help them simplify system design,” said company v-p semiconductors Laurent Monge. 7.5 GHz of analogue output ...

Pickering Electronics will demonstrate its two pole reed relays for high density designs at the Electronica exhibition in Munich next week (8 – 11 November). The series 115, 2 Form A relays can switch up to 15W, 1A and measuring 4mm x 10mm, the two-pole relay is only 50% larger than the single pole version. Two switch types are available. Both types have ...

Linear Technology has produced a high-power dual voltage reference, allowing the reference replace the circuit power supply regulator. Specs are excellent, with outputs offering 0.05% initial accuracy, 10ppm/°C temperature drift and 1.5ppm p-p of noise from 0.1 to 10Hz. With no capacitor on the noise reduction (NR) pin, voltage noise density is around 150nV/rt(Hz) until the bandwidth is limited by ...

LTC has introduced a high precision 32-bit SAR ADC. Many high performance applications, including data acquisition, industrial control and medical instrumentation, require both accuracy and speed. This is often achieved by using a high resolution delta-sigma ADC and a high speed SAR ADC in the same system. The LTC2508-32 simplifies such hybrid ADC system design by simultaneously providing both a ...

Semtech has introduced a 7-line surge-rated, 24V transient protection array for protecting industrial interfaces against transient voltage threats. The µClamp2417P offers a 10A (8×20µs waveform) surge immunity level in a small 2.6 x 2.6mm QFN package. It can be used for protecting industrial data interfaces from electrical transient threats including electrostatic discharge (ESD), electrical fast transients (EFT) and lightning surge ...

STMicroelectronics has introduced the TSX7 series of precision 16V op amps which the supplier claims can eliminate the need for trimming or calibration in the assembled circuit due to their low input-offset voltage, common mode rejection ratio and temperature drift. The op amps are available with an automotive-grade temperature range from -40°C to 125°C. Using an 18V technology, the TSX7 ...
