General Description
The MAX1245 12-bit data-acquisition system combines an 8-channel multiplexer, high-bandwidth track/hold, and serial interface with high conversion speed and ultra-low power consumption. It operates from a single +2.375V to +3.3V supply, and its analog inputs are software configurable for unipolar/bipolar and single-ended/differential operation.

FEATUREs
♦ Single +2.375V to +3.3V Operation
♦ 8-Channel Single-Ended or 4-Channel Differential Analog Inputs
♦ Low Power: 0.8mA (100ksps) 10µA (1ksps) 1µA (power-down mode)
♦ Internal Track/Hold, 100kHz Sampling Rate
♦ SPI/QSPI/Microwire/TMS320-Compatible 4-Wire Serial Interface
♦ Software-Configurable Unipolar or Bipolar Inputs
♦ 20-Pin DIP/SSOP Packages
