# Differential Amplifier circuit

I wanted to transform a differential signal to a single-ended signal using a differential amplifier. When I am reading the datasheets for fully differential amplifiers there are just single-ended/differential to differential cases shown.

Is this possible with fully differential amplifiers?

• Why do you want to use a differential amplifier? Normally you use a differential amplifier when you want a differential output. – kjgregory Nov 27 '17 at 15:33
• Oh okay, then this is my fault :D. So I just need a normal opamp I guess? – epgrape Nov 27 '17 at 15:34
• I would think so. There are a number of op-amp topologies you could use depending on your exact needs. – kjgregory Nov 27 '17 at 15:35
• Also search for instrumentation amplifier, or differential line driver / differential line receiver. – Vladimir Cravero Nov 27 '17 at 15:37

You can change the differential gain of the instrumentation amplifier simply by changing the value of one resistor: Rgain
