Hello,
Customer usually uses the VCC bipolar power (+/-15V) on TL074 for analog input application. However, since they plan to change the power design circuitry, the input bias power for TL074 would be changed to (+18V, -12V) or (+15V and -5V). We'd like to know if these input common ranges are ok for this application or not?
In the datasheet, it said the common-mode input voltage range is +/-11V as minimum value @+/-15V VCC bias power. Does it mean that the dropout voltage of input is 4V, correct? Is this fixed value of 4V no mater what input voltage level, right? and also, how about the output voltage swing range?
Application: Analog Input Circuitry for VFD.
Regards
Brian
