          2.7V to 5.25V, Low-Power, 8-Channel, Serial 10-Bit ADCs

          General Description The MAX148/MAX149 10-bit data-acquisition systems combine an 8-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 sample to 133ksps. Both devices’ ana
