MCQ Practice Question

Analog Electronics Operational Amplifiers

Rail-to-rail input/output op-amps are designed primarily to?

AOperate with signal ranges closer to the supply rails
BProvide infinite bandwidth
CEliminate all offset voltage
DOperate without power supplies

Correct Answer: A. Operate with signal ranges closer to the supply rails

Explanation: Rail-to-rail architectures extend input common-mode range and/or output swing close to the supply rails, useful at low supply voltages.
