TLV9144: TLV9144

Part Number: TLV9144

Tool/software:

Hi, I wonder if TLV9144 is a single supply or dual supply. I like to use this op amp in my circuit, where supply will be 10 VDC and Common (GND) and my input can go as low as +0.3 VDC. Thanks for the help.

TLV9144 can be used for both single or dual power rails. The table below is the operating voltage rail, which is up to 18Vdc for single rail. The input common mode voltage range will be operating fine for > +0.3V signal.

If you have other questions, please let me know.

Best,

Raymond

Hi Raymond, Thanks a lot for your response. If my application rail is 10VDC and GND. How low output can this op amp produce? GND+0.3V ? Thanks

Hi Nader,

200mV from GND should be suffice for the design margin. The op amp's datasheet is specified 200mV below GND, but this is typically said at room temperature. Over temperature, I would say the Vcm input voltage should be from GND to close to 10Vdc over the specified temperature range.

Best.
