3+ mon, 2+ week ago   (1197+ words) Voice of the Engineer Manufacturers of circuit-protection devices have significantly improved the performance of their safety components to protect electronic devices and equipment from a range of failures caused by electrical surges and electrostatic discharge (ESD), as well as overvoltage,…...

3+ mon, 3+ week ago   (356+ words) Voice of the Engineer Ground-referenced loads are common in industry. This circuit implements current loop conversions for them. Wow the engineering world with your unique design: Design Ideas Submission Guide Figure 1 In this 4/20mA to 0/20mA converter for grounded loads, R4 and RB…...

6+ mon, 2+ week ago   (521+ words) Voice of the Engineer My recent DI contribution (Another silly simple precision 0/20mA to 4/20mA converter) 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 standard two-terminal industrial…...

7+ mon, 1+ day ago   (166+ words) Voice of the Engineer Allegro Microsystems’ ACS37017 Hall-effect current sensor achieves 0.55% typical sensitivity error across temperature and lifetime. High accuracy, a 750‑kHz bandwidth, and a 1‑µs typical response time make the ACS37017 suitable for demanding control loops in automotive and industrial high-voltage…...
