MAX1249 Datasheet (Maxim)

MAX1249, 10-Bit ADCs

The MAX1248/MAX1249 10-bit data-acquisition systems combine a 4-channel multiplexer, high-bandwidth track/hold, and serial interface with high conversion speed and low power consumption.

They operate from a single +2.7V to +5.25V supply, and their analog inputs are software configurable for unipolar
