GENERAL DESCRIPTION
Easy interface to microprocessors is provided by the latched and decoded multiplexer address inputs and latched three-state outputs. The ML2258 enhancements are faster conversion time, true sample and hold function, superior power supply rejection, wider reference range, and a double buffered data bus as well as faster digital timing. All parameters are guaranteed over temperature with a power supply voltage of 5V ±10%. FEATURES
