Advantages and Disadvantages of Moving Iron Instruments


Advantages and Disadvantages of Moving Iron Instruments

Advantages

1.       The instrument can be used both on DC as well as on AC circuits.
2.       These instruments are cheap, robust and simple in construction.
3.       The instruments have high operating torque.
4.       The instruments are reasonably accurate.
5.       These instruments can withstand overload momentarily.

Disadvantages

1.       Scales of these instruments are not uniform because of pneumatic damping.

2.       Errors are introduced due to change of frequency I case of A.C.
3.       Errors are introduce due to hysteresis and stray magnetic field.

4.       Power consumption is high.

Using the TLP250 Isolated MOSFET Driver Explanation and Example Circuits

I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig. 2 - TLP250 Truth Table Fig. 1 clearly shows the input LED side and the receiving photodetector as well...

Audio signal processing IC for 1 5 V headphone stereo

General Description: The AN7500FHQ is a single chip IC optimum for a 1.5 V headphone stereo system including pre-amp., power amp. and Dolby B type noise reduction circuit. Current consumption in a Dolby circuit off mode has been drastically reduced and an operating supply voltage has also been lowered to 0.98 V. Much fewer external components  have been realized due to an integration of audio signal processing system into a single chip circuitry in a small outline package and space saving mounting of a set.
