The MAX1265/MAX1267 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 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).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 MAX1265 is offered in a 28-pin QSOP package, while the MAX1267 comes in a 24-pin QSOP. For pin-compatible +5V, 12-bit versions, refer to the MAX1266/MAX1268 data sheet.ApplicationsData Acquisition SystemsData LoggingEnergy ManagementIndustrial Controls SystemsPatient MonitoringTouch Screens
