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. The differential comparator design provides low power supply sensitivity to DC and AC variations. The voltage reference can be externally set to any value between ground and VCC, thus allowing a full conversion over a relatively small span. All parameters are guaranteed over temperature with a power supply ...
