Ashutosh Sapre

Ashutosh Sapre lives and works in a large city in western India. Drifting uninspired through an EE degree way back in the late nineteen eighties, he was lucky enough to stumble across and be electrified by the Art of Electronics 1 and 2.

Cut to now, he is a confirmed circuit addict, running a business designing, manufacturing and selling industrial signal processing modules. He is proud of his many dozens of design pads consisting mostly of crossed out design ideas.

  1. An LM317-based 0-20 mA to 4-20 mA 2-wire converter
    My recent DI contribution (Another silly simple precision 0/20 mA to 4/20 mA converter, Ref. 1) used the LM337 regulator in a novel circuit arrangement to translate an input 0-20 mA current source into a 4-20 mA two-wire transmitter current loop (a...

  2. Another silly simple precision 0-20mA to 4/20mA converter
    A recent Design Idea (DI), “Silly simple precision 0/20 mA to 4/20 mA converter,” (Ref. 1) by prolific DI contributor Stephen Woodward uses the venerable LM337 regulator in a creative configuration along with a few passive components, to translate an input...
