MAX1261 - Maxim Integrated

MAX1261 12-Bit ADC

The MAX1261/MAX1263 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. They operate with a single +3V analog supply and feature a VLOGIC pin that allows them to interface directly with.
