Harsh environment isolated current sense amp from Si Labs

Silicon Labs has introduced an isolated current sense amplifier for delivering current shunt measurement for power control systems operating in harsh environments such as industrial motor drives, solar inverters, high-voltage power converters, UPS and electric/hybrid-electric vehicle (EV/HEV) systems.

Measuring current on high-voltage rails with a…

Contactless position sensor designed for reliability

A contactless rotary position sensor from ams is designed as a replacement for conventional rotary encoders.

“In devices which use rotary knobs, the AS5601 and its paired magnet may replace a rotary encoder without any change to the host microcontroller or its application software,” said the supplier.

The sensor is…

How to design a supercapacitor charger with balancing

As the cost to produce supercapacitors (SCAPs, or ultracapacitors) continues to decline, they are carving out a niche in the marketplace between conventional capacitors and batteries. And, although supercaps require some “care and feeding,” they are replacing batteries in data storage applications requiring high current/short duration backup power.

Op amp runs off 140V supply

Linear Technology’s latest precision operational amplifiers can be operated on a supply voltage up to 140V (±70V).

The dual LTC6091 features separate output disable pins, making it useful in high voltage multiplexed applications.

The decompensated single LTC6090-5 amplifier offers higher speed and is stable at a gain of…

No substitute for a designer's experience, says Altium

We must give engineers to draw on their experience when starting new designs, writes Robert Huxel When an electronic design engineer creates a working environment, they don’t first make a bench, and then a power supply, and then a DMM, and then an oscilloscope or frequency counter. They procure…
