The circuits were designed using two A/D converters to create a voltmeter and ampermeter. The circuits are designed with the combination of CA3161E and CA3162E to imposing a complete 3-digit display ...
This is a take-off on Mr. Marian’s “Simple Micro Ampere Meter Circuit” that utilizes active circuitry and an analog meter to make sensitive DC current measurements. A reader subsequently asked if it ...
