Micro Linear ML2252

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. 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.

GENERAL DESCRIPTION

Easy interface to microprocessors is provided by the latched and decoded multiplexer address inputs and a double buffered three-state data bus. 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 voltage of 5V ±10%. The device is suitable for a wide range of applications from process and machine control to consumer, automotive, and telecommunication applications.
