What is a single ended device that produces the state opposite to the input called?
A
Buffer
B
Inverting buffer
C
Op-Amp
D
None of the above
Explanation: 

Detailed explanation-1: -The inverting buffer is a single-input device which produces the state opposite the input. If the input is high, the output is low and vice versa. This device is commonly referred to as just an inverter.

Detailed explanation-2: -A type of operational amplifier which generates an amplified output signal that is 180° out of phase with the input signal is called an inverting amplifier.

Detailed explanation-3: -An inverting op amp is an operational amplifier circuit with an output voltage that changes in the opposite direction as the input voltage. In other words, it is out of phase by 180o

Detailed explanation-4: -A non-inverting amplifier produces an output signal that is in phase with the input signal, whereas an inverting amplifier’s output is out of phase. Both the inverting and non-inverting op amps can be constructed from one op amp and two resistors, just in different configurations.

Detailed explanation-5: -ADI single-ended to differential amplifiers enable the processing of both single-ended inputs to complementary differential outputs or differential inputs to differential outputs. This provides a convenient solution when interfacing with analog-to-digital converters (ADCs).
