What type adc is to be interfaced with lpc2478

&lt;b&gt;my project involves acquisition of physiological signals like
temperature,ecg,these signals to be amplified and converted to
digital form.Digital signals are to processed by arm lpc2478 and to
be displayed on lcd.So,i need a suggestion for choosing adc to
interface lpc2478 and what type of communication is needed for
interfacing external adc with arm lpc2478.&lt;br /&gt;
how much resolution is required for displaying real time display of
ecg.&lt;/b&gt;&lt;/p&gt;

The external ADCs we&amp;#39;re using have a SPI interface alright, but
are limited to 12 bit...&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: lpc 2478 interfacing with adc</title><link>https://community.arm.com/thread/104481?ContentTypeID=1</link><pubDate>Sat, 25 Dec 2010 08:38:40 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:41a7e163-4a3e-49d9-84d7-e37153b572a1</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
You wanted your name in bold, but &amp;quot;forgot&amp;quot; to mention such tiny
details like that you needed 16-bit resolution, 200ksps (still no
mention if that is for each channel or in total), SPI interface, ...
Are there more things you have &amp;quot;forgotten&amp;quot; to mention?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: lpc 2478 interfacing with adc</title><link>https://community.arm.com/thread/78905?ContentTypeID=1</link><pubDate>Sat, 25 Dec 2010 05:15:52 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:f7f5df27-40c4-4bed-a0b2-20a0ad714c7e</guid><dc:creator>sravan jaini</dc:creator><description>&lt;p&gt;&lt;p&gt;
my project involves acquisition of physiological signals like
temperature,ecg,these signals to be amplified and converted to
digital form.Digital signals are to processed by arm lpc2478 and to
be displayed on lcd.For this i need 8 channels,200ksps,spi
interfacing,16 bit resolution for adc.These specifications are not in
lpc2478.So,i need a suggestion for choosing adc to interface
lpc2478&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: lpc 2478 interfacing with adc</title><link>https://community.arm.com/thread/66130?ContentTypeID=1</link><pubDate>Sat, 25 Dec 2010 05:00:38 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:e80aa780-f1d3-45a8-b1af-ae459524d41c</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
The type that solves the needs.&lt;/p&gt;

&lt;p&gt;
What was wrong with the ADC already available? Too few inputs? Too
low resolution? Too slow sample rate? Wrong voltage range?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
