Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give a detailed discussion on Introduction to LM4040. LM-4040 is specially designed for an accurate micro-power shunt voltage reference. These voltage references includes the standards of 2.5V, 3V % 5V respectively. LM-4040 has three different grade A, B and C grades and they have o.1%, o.5% and 1% tolerances respectively. This device is available in different packages and each package has different individual dimension which will be explained later. We can achieve an excellent performance from this device when it is operating at the current ranging from 60uA to 15mA and its temperature coefficient is 20 ppm per degree. In order to maintain good stability level the device's design is much tolerant to capacitive loads. LM-4040 has several different features e.g. low output noise, no output capacitor, good output voltage tolerance, large current operating ranges, low temperature coefficient, lead (Pb) free, halogen free, antimony free etc. It can be used at different places like battery powered systems, portable communication devices, notebook and palm-top computers, portable instrumentation, accurate power supply, data acquisition systems etc. The further detail about LM 4040 will be given later in this tutorial.
