Maxim Integrated MAX1290

the MAX1290 has eight input channels and the MAX1292 has four input channels (four and two input channels, respectively, when in pseudo-differential mode). The MAX1290/MAX1292 tri-states INT when CS goes high. The MAX1290 is available in a 28-pin QSOP package, while the MAX1292 comes in a 24-pin QSOP.

GENERAL DESCRIPTION

The MAX1290/MAX1292 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, 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 parallel 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-differential operation. In single-ended mode, Excellent dynamic performance and low power, combined with ease of use and small pack...
