BC557 PNP Transistor General Purpose

BC556, BC557 and BC558 PNP Amplifier Transistors are not only popular today but very ancient, it is used as a General Purpose device and a popular LED control in small products.

BC557 PNP Transistor - Amplifier

This Silicon device along with some others replaced Germanium Devices in Preamplifiers and Portable Transistor Radios  and Portable Tape Recorders. A Complement is the BC547 NPN General Purpose Transistor. Now for Specs 45V, 100mA, 200 beta approx.

BC557 PNP Transistor General Purpose

I will explain in a way most can comprehend. Do not use this for circuits working around 30-40 Volts. Use it for circuits upto 24 volts on the safer side. (45 V max rating)

Do not subject the base emmiter (diode path ) to any kind of reverse bias. That includes kickback from coils of relays or solenoids. This will damage the device, protect with a diode if needed.

Do not work it hot, it is not a metal device, use it for small signal. Reed Relay driving is possible, Single LED drive is also ok. Microphone Amplifiers, Bass, Treble and Presence controls. LED Flashers, Graphic Equalizers are things you could make with this, using Filter Circuits.

Continuous current rating is 100mA, this is fine if transistor is saturated or fully on, when voltage across device is very less and current is 100mA. Power Dissipation is tolerable. If Transistor is just partially ON or Switching fast, The Power Dissipation can peak and eventually damage the device. The device can manage to survive say 500 mW or a little more, but remember that the battery is draining fast.

A 200 Beta is pretty good, it depends on temperature, voltage and other factors. 100uA base drive can can turn on a LED at 20mA in the collector path. You can drive a LED from Opamp or Logic IC using this device, just add a 22k in series to the base.

Design products that are safe, last long and use very little power. That is pretty Green.

MAX1169 ADC Analog-to-Digital converter

What is the use of a Robot, which cannot perceive its environment in detail. Where can a Control system be effective, if it does not get a "feedback" about its actions. How could one do Analysis and Research or Verify, when he cannot Measure a parameter with good accuracy and resolution.

ADC are the Eyes and Ears for a uC, this brings the Real world as Numbers within the CPU. Without ADC a uC is like a Frog in the Well and has to create an Imaginary World for himself. That is beyond the scope of Engineering.

MAX1169 ADC and PIC Microcontroller

Bring your favorite PIC Microcontroller to his senses. Give him an ability to Perceive the Reality around him. Get him an Analog to Digital Converter and don't forget to code.

Interfacing the MAX1169 ADC to a PIC Microcontroller - Maxim

MAX1169 ADC is better than 4 1/2 Digit Value. For me the Intersil chip is a Benchmark. Beyond 5 1/2 Resolution may be needed only for Scientific Research.

I would say, 2 1/2 is like Analog Meters/Bar Graphs, 3 1/2 for Control systems, 4 1/2 for T&M and beyond 5 1/2 is for R&D.

Abstract: This application note describes how to interface a MAX1169 analog-to-digital converter (ADC) to a PIC microcontroller. It includes an example circuit and software for a PIC18F442. The software contains function calls to interface the ADC to the PIC microcontroller using the internal MSSP I²C port at 400kHz.

This Mux is useful for making a Datalogger or Expanding the I/O of a PLC analog unit. A Multi-Point process scanner, an analog Sample and hold system are some ideas. If you have many testpoints to monitor an you have a Embedded System with one analog input then you could think of this. Remember to protect the inputs and isolate if required. Real world parameters pose real hazards.

That way Air Insulation makes Isolation good. The Line of Isolation has to be observed in all SMPS under Magnetics and Optos. Creepage of HV can occur due to Grime and Humidity on PCB, use RTV Silicone Rubber or Epoxy impregnation to make your product Industrial or Military Grade. - delabs design Notes

4N35 Optocoupler Vishay

Other Features - Interfaces with common logic families, Input-output coupling capacitance < 0.5 pF, the low level capacitance means you can switch this opto at high speeds.
