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.

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.

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)
