Description
The MAX194, with an external reference (up to +5V), offers a unipolar (0V to VREF) or bipolar (-VREF to VREF) pin-selectable input range. Separate analog and digital supplies minimize digital-noise coupling.
The chip select (active-low CS) input controls the three-state serial-data output. The output can be read either during conversion as the bits are determined, or following conversion at up to 5Mbps using the serial clock (SCLK). The end-of-conversion (active-low EOC) output can be used to interrupt a processor, or can be connected directly to the convert input (active-low CONV) for continuous, full-speed conversions.
The MAX194 is available in 16-pin DIP, wide SO, and ceramic sidebraze packages. The output data format provides pin-for-pin and functional compatibility with the 16-bit MAX195 ADC.
