Differential Amplifier is an input stage of every op-amp

Generally, if input stage of an operational amplifier is realized as BJT tr ansistor differential amplifier, op-amp has smaller slew rate, smaller volt age offset and better CMRR. If it's realized as JFET transistor based diffe rential amplifier, voltage offset is higher, CMRR is smaller but slew rate is better.
