Of course, one could almost accomplish this by just using an Arduino Due, which has a 12-bit A/D converter (almost, because it has a lower reference voltage of 3.3 V).

Caption Dual USB inputs and 12-bit analog I/Os. The Due is also the first Arduino to feature a built-in digital-to-analog converter — two, in fact.

Fürstenfeldbruck, Germany: According to National Semiconductor, its ADC12D1800 is the industry’s fastest 12-bit analog-to digital converter (ADC). At 3.6 Gsamples/s, it is 3.6 times faster than ...

The LTC2242-12 costs $59 each in 1000-piece quantities. The 210- and 170- Msample/s versions cost $42 and $35. The 10-bit versions cost $39, $32, and $25. Linear Technology www.linear.com ...

Dallas, Texas — Texas Instruments has introduced an ADC that combines 12 bits of resolution with a 1-GSPS sampling rate, effectively doubling the amount of signal bandwidth that can be captured in a ...
