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.

Furthermore…

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…

Bi-directional 3MHz dc-dc charges Li-ion and supplies 5V

Aimed at devices that can both be charged from USB, and supply 5V through the same connector for USB on-the-go (OTG), Fairchild has released a bidirectional dc-dc converter.

FAN54015 is a 3MHz synchronous converter, capable of supplying 1.45A to the cell at a programmable float from…

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…

16bit PICs get more analogue, operation, and fewer pins

Microchip has introduced the PIC24F ’KM’ family with “a new level of integrated analogue functionality”, said the firm, “including a 12bit ADC with threshold detection, 8bit DACs for control loops, precision comparator references, and op-amps.” For motor-control, power-supply and lighting, the microcontrollers have the firm’s multiple…
