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

LT1528 High current, Variable Voltage Regulator

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.

Basic Voltage Regulators Variable voltage regulators, set output regulators, we give you the whole breakdown. Perfect for use with an external wall-wart power supply.

Microcontrollers

LPC2103 Low cost 70MHz ARM7TDMI-S FLASH Microcontroller from Philips.

Op Amps

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

LT1168 Programmable-Gain Precision Instrumentation Amplifier - Low Power, Single Resistor Gain Programmable, Precision Instrumentation Amplifier

LT1114 Low Power Precision OP-Amps are used for amplification and filtering of the signal - Dual/Quad Low Power Precision, Picoamp Input Op Amps
