The MAX11254 is a 24-bit, low-power delta-sigma ADC with superior noise performance. It incorporates a highly stable internal oscillator that provides the system clock that supports the digital and ...

SPI is a very useful and flexible standard, but its flexibility stems from its simplicity. Four channels of unidirectional moderate speed isolation will handle SPI to clock rates of a couple of MHz.

With all the amazing and wonderful things a Raspberry Pi can do, it is sorely lacking a dedicated ADC chip. Sure, you can wire up an ADC via SPI or even I2C with a little work, but still. It would be ...
