Maxim Integrated MAX1261BEEI T

Description
The MAX1261/MAX1263 are low-power, 12-bit analog-to-digital converters (ADCs) featuring:
Successive-approximation ADC
Automatic power-down
Fast wake-up (2µs)
On-chip clock
2.5V internal reference
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.

Features
User-adjustable logic level ( 1.8V to 3.6V)
Internal 2.5V reference
Software-configurable analog input multiplexer:
8-channel single-ended/4-channel pseudo-differential (MAX1261)
4-channel single-ended/2-channel pseudo-differential (MAX1263)
Software-configurable unipolar/bipolar inputs
Low power:
1.9mA (250ksps)
1.0mA (100ksps)
400µA (10ksps)
2µA (shutdown)
Internal 3MHz full-power bandwidth track/hold
Byte-wide parallel (8 4) interface
Small footprint:
28-pin QSOP (MAX1261)
24-pin QSOP (MAX1263)
