Maxim Integrated MAX1267BCEG

Description
The MAX1265/MAX1267 are low-power, 12-bit analog-to-digital converters (ADCs) featuring a successive-approximation ADC, automatic power-down, fast wake-up (2us), an on-chip clock, 2.5V internal reference, and a high-speed 12-bit parallel interface. They operate with a single 2.7V to 3.6V analog supply. Power consumption is only 5.4mW at the maximum sampling rate of 265ksps. Two software-selectable power-down modes enable the MAX1265/MAX1267 to be shut down between conversions; accessing the parallel interface returns them to normal operation. Powering down between conversions can reduce supply current below 10μA at lower sampling rates.
Both devices offer software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation. In single-ended mode, the MAX1265 has six input channels and the MAX1267 has two (three input channels and one input channel, respectively, when in pseudo-differential mode).
