MAX1294/MAX1296
General Description
The MAX1294/MAX1296 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 MAX1294/MAX1296 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 MAX1294 has six input channels and the MAX1296 has two (three...
