数据手册.pdf\+ 2.7Low功耗， 8通道，串行12位ADC +2.7Low-Power, 8-Channel, Serial 12-Bit ADCs
General Description
The MAX146/MAX147 12-bit data-acquisition systems combine an 8-channel multiplexer, high-bandwidth track/hold, and serial interface with high conversion speed and low power consumption. The MAX146 operates from a single +2.7V to +3.6V supply; the MAX147 operates from a single +2.7V to +5.25V supply. Both devices’ analog inputs are software configurable for unipolar/bipolar and single-ended/differential operation.
