General Description
The MAX1261/MAX1263 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, byte-wide parallel interface. They operate with a single +3V analog supply and feature a VLOGIC pin that allows them to interface directly with a +1.8V to +5.5V digital supply.
