MAX144BCUA+ [Analog Devices]

The MAX144/MAX145 are low-power, 12-bit successive-approximation ADCs with a 7.4µs conversion time, automatic power-down, fast wake-up (2.5µs), on-chip clock, and a high-speed 3-wire serial interface. They operate from a single +2.7V to +5.25V supply and feature two single-ended channels (MAX144) or one pseudo-differential channel (MAX145). Power consumption is only 3.2mW at 108ksps, with automatic shutdown reducing current to 0.2µA. They are ideal for battery-powered and data-acquisition applications.
