ML2252*, ML2259** µP Compatible 8-Bit A/D Converters with 2- or 8-Channel Multiplexer
GENERAL DESCRIPTION
The ML2252 and ML2259 combine an 8-bit A/D converter, 2- or 8-channel analog multiplexer, and a microprocessor compatible 8-bit parallel interface and control logic in a single monolithic
CMOS device.
Easy interface to microprocessors is provided by the latched and decoded multiplexer address inputs and a double buffered three-state data bus.
These analog-todigital converters allow the microprocessor to operate completely asynchronous to the converter clock.
The built in sample and hold function provides the ability to digitize a 5V, 50kHz sinewave to 8-bit accuracy.
