19-1066; Rev 0; 6/96 +2.375V, Low-Power, 8-Channel, Serial 12-Bit ADC ________________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. The 4-wire serial interface directly connects to SPI™, QSPI™, and Microwire™ devices without external logic. A serial strobe output allows direct connection to TMS320-family digital signal processors.
