Introduction
The LM741 series is general-purpose operational amplifiers that feature improved performance over industry standards like the LM709. This high-pace op-amp LM-741 is a direct, plug-in replacement for the 709C, LM201, MC1439, and 748 in most programs. The operational amplifiers offer many features which make their utility nearly foolproof overload safety at the input and output. The LM741C2 Channel Arduino Relay Board Module op-amp amplifier is the same as the LM741 and LM741A besides that the LM741C has their overall performance ensured over a 0°C to +70°C temperature variety, as opposed to −55°C to +125°C.
Features of LM741 Operational Amplifier
- 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 latch-up when the common-mode range is exceeded.
- Minimum, normal, and maximum Power Consumption for this IC is ±10v, ±15v, and ±22v respectively.
- The operating temperature should be -50 to 125 ˚C.
- Supply current – 1.7 to 2.8mA.
