Overview

The MAX1295/MAX1297AEEG low-power, 12-bit analog-to-digital 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 +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 MAX1295/MAX1297AEEG 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 MAX1295 has six input channels and the MAX1297AEEG has two (three input channels and one input channel, respectively, when in pseudo-differential mode). Excellent dynamic performance and low power, combined with ease of use and small package size, make these converters ideal for battery-powered and data-acquisition applications or for other circuits with demanding power-consumption and space requirements. The MAX1295/MAX1297AEEG tri-states active-low INT when active-low CS goes high. Refer to MAX1265/MAX1267 if tri-stating active-low INT is not desired. The MAX1295 is offered in a 28-pin QSOP package, while the MAX1297AEEG comes in a 24-pin QSOP. For pin-compatible +5V, 12-bit versions, refer to the MAX1294/MAX1296 data sheet.
