1 / 20 page General Description The MAX1290/MAX1292 low-power, 12-bit analog-to- digital converters (ADCs) feature a successive-approxi- mation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high-speed, byte-wide parallel interface. The devices operate with a single +5V analog supply and feature a VLOGIC pin that allows them to interface directly with a +2.7V to +5.5V digital supply. Power consumption is only 10mW (VDD = VLOGIC) at a 400ksps max sampling rate. Two software-selectable power-down modes enable the MAX1290/MAX1292 to be shut down between conversions; accessing the par- allel interface returns them to normal operation. Powering down between conversions can cut supply current to under 10µA at reduced sampling rates. Both devices offer software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differen- tial operation. In single-ended mode, the MAX1290 has eight input channels and the MAX1292 has four input channels (four and two input channels, respectively, when in pseudo-differential mode). Excellent dynamic performance and low power, com- bined with ease of use and small package size, make these converters ideal for battery-powered and data- acquisition applications or for other circuits with demand- ing power consumption and space requirements. The MAX1290/MAX1292 tri-states INT when CS goes high. Refer to MAX1262/MAX1264 if tri-stating INT is not desired. The MAX1290 is available in a 28-pin QSOP package, while the MAX1292 comes in a 24-pin QSOP. For pin- compatible +3V, 12-bit versions, refer to the MAX1291/ MAX1293 data sheet.
