LM741 Operational Amplifier IC
The LM741 series are general purpose operational amplifiers which feature improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439, and 748 in most applications. The amplifiers offer many features which make their application nearly foolproof: overload protection on the input and output, no latch-up when the common-mode range is exceeded, as well as freedom from oscillators.
Pin Description
- Pin-1 is Offset null.
- Pin-2 is Inverting (-) i/p terminal.
- Pin-3 is a non-inverting (+) i/p terminal.
- Pin-4 is -ve voltage supply (VCC)
- Pin-5 is offset null.
- Pin-6 is the o/p voltage.
- Pin-7 is +ve voltage supply (+VCC)
- Pin-8 is not connected.
Features
- LM741 has only one op-amp inside, there are some op-amp IC’s having more than one op-amp like LM358, LM148, LM248, LM348
- Provided with short circuit and overload protection.
- Low power consumption.
- Large common mode rejection ratio (CMRR) and differential voltage ranges.
- No external frequency compensation is required.
- Prevent from latch-up when the common-mode range is exceeded.
- Minimum, normal and maximum Power Consumption for this IC is ±10v, ±15v and ±22v respectively.
- Operating temperature should be -50 to 125 ˚C.
- Supply current – 1.7 to 2.8mA.
