The INA250 from Texas Instruments is a voltage-output current-sensing amplifier integrated with a 0.002 Ω resistor — all within a 5.00 × 4.40 mm TSSOP16 package. It’s not the first time a device like ...
AMS’s latest reference design board measures current to an accuracy of ±1% by monitoring the voltage drop across a copper track on a printed-circuit board (PCB). The new technique uses AMS’s AS8510 ...
