Product Summary

The MAX1290BCEI+T is a low-power, 12-bit analog-todigital converter (ADC). It features a successive-approximation ADC, automatic power-down, fast wake-upm(2μs), an on-chip clock, +2.5V internal reference, and a high-speed, byte-wide parallel interface. The MAX1290BCEI+T operates 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.
