Analogue / Linear / Mixed Signal ICs

A dual precision op amp from STMicroelectronics is designed to have a low and temperature-stable input-offset voltage. The TSZ182 op amp has a chopper-stabilised design and a 3MHz gain-bandwidth. The offset voltage of 25µV at 25°C is designed for high measurement resolution and accuracy without external trimming components. Offset drift is specified by the supplier at less than 100nV/°C. The ...

Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut stand-by drain in sensor nodes

Rohm Semiconductor has developed an evaluation kit for motor driver devices which is designed as a ‘shield’ to plug directly into the Arduino open source board. There different versions of the kit for the supplier’s various stepper motor driver ICs– from standard, micro step, low voltage to high voltage. It covers supply voltages from 8V to 42V, enables up to 2.5A per phase, as well as micro-stepping ...

Maxim has designed a high-sides switch that can handle back-EMF from any inductance, regardless how much energy it has stored. MAX14913 includes eight of the switches, which can operate loads at up to 24V (36Vmax) and 500mA. “Designers of industrial controllers can safely drive and demagnetise any inductive load for Industry 4.0 applications,” claimed the firm at Electronica this week. ...

Infineon has developed an Arduino shield to demonstrate the potential of its 24V Profet protected power switches. Called the Protected Switch Shield, it is also compatible with the firm’s own XMC microcontroller kits which borrow the Arduino form factor. The shield runs from 8-36V and provides a driver circuit with logic level inputs, load diagnosis and current sense. The power switches ...

Allegro has developed a range of high-current automotive-grade current sensors in packages only 1.5mm thick. The Hall sensors are differential to reject common-mode fields  – from nearby current-carrying conductors, for example. The devices consist of a precision low-offset linear Hall circuit with a copper conduction path located near the die (see photo). Applied current generates a magnetic field which the ...

Texas Instruments has released a slew of 10Gbit/s USB Type-C products. TUSB1046-DCI, for example, is a VESA USB Type-C Alt Mode re-driving switch supporting USB 3.1 data rates up to 10Gbit/s and DisplayPort 1.4 up to 8.1Gbit/s for downstream facing port (Host). 10Gbit/s is ‘SuperSpeedPlus’, compared with 5Gbit/s ‘SuperSpeed’. The device is used for configurations C, D, E, and F ...

Silicon Radar of Frankfurt introduces development kits for its GHz CMOS radar MMICs, which are built using SiGe or SiGe:C from IHP.

Today Intersil claims to have the industry’s lowest power 14-channel programmable gamma buffer for automotive TFT-LCD displays.

US-based developer of gallium arsenide (GaAs) monolithic microwave integrated circuits (MMICs), Custom MMIC is represented in the UK by Aspen Electronics, and its microwave amplifiers, switches and mixers are on show this week at European Microwave Week (EuMW) in London. These include a SP3T switch, the CMD234C4, which provides an isolation of 40dB at 10GHz and insertion loss of 2dB. ...
