Comprised of two precision op amps (MAX4236), a voltage reference (MAX6143), a NAND gate, and associated components, this DC-voltage detector circuit asserts a digital output signal when the input is ...
A function often needed in industrial and scientific applications is detecting the presence (or absence) of dc voltages in such components as safety interlocks and automatic sequencers. To detect the ...
The present IP is a VCC Detector (VDT) circuit, which prevents the possibilities of causing Flash writing failure or internal operation failure by uns ...
This design idea showcases a circuit that detects RF “bugs,” such as hidden wireless cameras, eavesdropping microphones, and other spying devices that emit RF frequencies in the 100MHz to 3000MHz ...
Fig 1. This zero-crossing detector circuit generates the control pulses needed to turn on triacs that require negative pulses for switching. Fig 2. Designers can use ...
