GENERAL DESCRIPTION
The MAX1266/MAX1268 low-power, 12-bit analog-todigital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high-speed 12-bit parallel interface. They operate with a single +5V analog supply. Power consumption is only 10mW at the maximum sampling rate of 420ksps. Two software-selectable powerdown modes enable the MAX1266/MAX1268 to be shut down between conversions; accessing the parallel interface returns them to normal operation. Powering down between conversions can reduce supply 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 MAX1266 has six input channels and the MAX1268 has two (three input channels and on
