Typical Applications UNIVERSAL LOGIC LEVEL SHIFTER The output of LMV7275 is an unconnected drain of an NMOS device, which can be pulled up, through a resistor, to any de- sired output level within the permitted power supply range. Hence, the ...

NEGATIVE PEAK DETECTOR For the negative detector, the output transistor of the com- parator acts as a low impedance current sink. Since there is no pull-up resistor, the only discharge path will be the 1MΩ resistor and any load impedance ...
