"Ferrites? I don't know much about 'em, I only use ferrites in switching regulators." --National Semiconductor's Bob Pease<br />
<br />
Can be replaced in many circumstances with an impedance inverter using only an opamp, a capacitor, and a few resistors.<br />

<div>== Digital Potentiometers ==<br />
[[Digital Potentiometers|Digital Potentiometers(AD5204)]]<br />
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.<br />

| 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.<br />

| Precision Voltage Regulator. Can be used as fixed or floating, variable, linear or switching. <br />
'''NOTE:''' Only the DIP-14 version (image) has the Vz pin, which is used for negative regulators. The Metal Can and the Flat-Pack do not have enough pins so exclude the Vz.<br />
