Digital Potentiometers

Digital Potentiometers(AD5204) The digital Potentiometers made by analog devices (AD5204) has 255 positions can be adjusted by the microcomputer that can receive commands from the computer. This is a great way for analog circuitry to have digital control. This is a chip with 4 digitally controlled POTs and the pots can be daisy chained to have multiple chips controled by a single SPI interface.


Voltage Regulators

Linear Regulators
LT1528
LT1528
High current, Variable Voltage Regulator
TPS V-Reg
TPS V-Regs
These are 3.3V and 5V LDO, Low-Noise Voltage Regulators. Very small SOT-23 SMD package. 150mA max current. Best used in battery applications.

Extremely Efficient, 120mA Flyback Switching Regulators.

Microcontrollers

I've written a little about the various kinds of microcontrollers at Wikibooks: Embedded Systems. --DavidCary 06:15, 10 March 2007 (PST)

Op Amps

Op amps and instrumentation amps.

op amps: great for amplifying weak signals from sensors to a more useful level. Also used in filters, integrators, etc.

  • Wikibooks:Op-Amps has a "quick design process" using Daisy's theorem: "The sum of the gains = +1 in a properly-designed op amp circuit."

logic gates

There are hundreds of other specialized logic gates. Here we only list the ones we actually use in some Open Circuit Project:

  • 74HC595 eight bit shift register with output latch (used for POV display)
