What is UA741CN?
The UA741CN device is a general-purpose operational amplifier featuring offset-voltage null capability. The high common-mode input voltage range and the absence of latch-up make the amplifier ideal for voltage-follower applications.
What is the gain of LM741?
The LM741 has a GBW around 1MHz (but not listed in this datasheet). This means that with a 1MHz input the max gain is one (the gain drops off as frequency increases). Actually the gain is less than one because GBW is defined as the 3db point (i.e. where the voltage drops to 0.707 of its original value).
What is the CMRR value of μa741?
90dB
For 741IC, CMRR is 90dB. The change in the op-amp’s offset voltage caused by variations in supply voltage is called SVRR. The change in supply voltage can be denoted by dV and the corresponsing change in input ffset voltage can be denoted by dVio. For 741 IC, SVRR = 150uV/V.
What is an op amp and what does it do?
What is an Operational Amplifier (Op-amp)? An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.
What is UA741?
The UA741 is a high performance monolithic operational amplifier constructed on a single silicon chip. It is intended for a wide range of analog applications. The high gain and wide range of operating voltages provide superior performances in integrators, summing amplifiers and general feedback applications.
Why Op-Amp is called 741?
It was first manufactured by Fairchild semiconductors in the year 1963. The number 741 indicates that this operational amplifier IC has 7 functional pins, 4 pins capable of taking input and 1 output pin.
How much current can an op-amp sink?
A typical op-amp can be expected to continuously sink or source not more than 30 or 40 mA, though some parts can handle closer to 100 mA, and others will struggle to give you 10 mA.
Why do we use 741?
IC 741 Op Amp can provide high voltage gain and can be operated over a wide range of voltages, which makes it the best choice for use in integrators, summing amplifiers and general feedback applications. It also features short circuit protection and internal frequency compensation circuits built in it.
