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.

* [[Microchip]] PIC 8 bit FLASH microcontrollers
 
* Microchip dsPIC 16 bit FLASH microcontrollers ( [[DsPIC30F 5011 Development Board]] )

== Op Amps ==
 
 
 
Op amps and instrumentation amps.
 
 
 
[[op amp]]s: great for amplifying weak signals from [[sensors]] to a more useful level. Also used in filters, integrators, etc.

* [[LT1114|LT1114 Low Power Precision OP-Amps]] are used for amplification and filtering of the signal - Dual/Quad Low Power Precision, Picoamp Input Op Amps
 
* [http://en.wikibooks.org/wiki/Electronics/Op-Amps 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."''

* 74HC595 eight bit shift register with output latch (used for POV display)
 
 
 
== RF ICs/Modules ==
 
 
 
[http://www.linxtechnologies.com/ Linx Technologies] makes several low power RF transmitter/receiver chips. Their range is around 500' - 1000'. They are geared for one way communication only, like keyless entry systems. They also make several serial encoding chips that make the wireless communication more secure/crack proof. Their latest chip, the HS series, is based upon the SkipJack algorithm developed by the NSA.

== ADC analog to digital converter ==
 
 
 
There are a huge variety of ADCs available.
 
 
 
If you need 10 bits or less of resolution,
 
counter-intuitively,
 
it costs less to buy an ADC plus a microcontroller on one chip
 
than to buy a stand-alone ADC.
 
 
 
* ATTINY13V -- lowest-price chip I know of with at least one 10 bit ADC
 
* ATTINY261 -- lowest $/ADC chip I know of
 
* LPC2101FBD48 -- lowest-price 32-bit microcontroller I know of with at least one internal 10 bit ADC
 
 
 
Many people (*) do EKGs with only 10 bit converters.
 
 
 
The [[Programmable Chip EEG]] might need more bits of resolution.
 
 
 
What low-cost ADC are available with at least 12 bits?
 
* $2.50 MCP3301 has 1 ADC input (13 bits)
 
* $3.50 MCP3302 has 2 ADC input (13 bits)
 
* $3.50 MCP3204 has 4 ADC input (12 bits)
 
* $4 MCP3208 has 8 ADC input (12 bits)
 
* $8 dsPIC30F 2011 microcontroller has 8 ADC inputs (12 bits). See [[dsPIC30F 5011 Development Board]] for details.
 
* $6 CY8C27443 Cypress PSoC microcontroller has 4 ADC inputs (14 bits) -- but what is the sampling rate? Also has 4 DAC outputs (9 bits).
 
 
 
* $56 biosemi used analog devices AD7716: four independent, simultaneous 22 bit ADCs.
 
* [http://www.maxim-ic.com/appnotes.cfm/an_pk/885 the Maxim MAX1460 includes a 16-bit ADC, 12-bit DAC], a programmable gain amp (PGA), temp sensor, and 16-bit processor. (Alas, its program is in unchangeable ROM).
 
* Analog Devices AduC812: 200kHz 12-bit ADC, 12-bit DAC, and flash-based 8051 MCU core.
 
 
 
''I am astonished to discover that (a few) microcontrollers include 12 bit or more ADCs. Are there others? --[[User:DavidCary|DavidCary]] 18:48, 28 August 2007 (PDT)''
