The MAX11192 is a 12-bit resolution dual-channel SAR ADCs with simultaneous sampling at 2Msps with differential inputs. Available in a tiny 16-pin, 3 x 2mm ultra TDFN package, this ADC delivers excellent static and dynamic performance while operating from a supply voltage of 3.0V to 5.25V. An integrated reference further reduces board area and component count. The MAX11192 outputs conversion data using an SPI-compatible serial interface with a dual DOUT bus. Specifications apply over the extended industrial temperature range of -40°C to +125°C on all terminal pins for driving larger loads.
