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.

FEATURES

■Conversion time (fCLK= 1.46MHz); 6.6μs

■Total unadjusted error; ±1/2LSB or ±1LSB

■No missing codes

■Sample and hold; 390ns acquisition

■Capable of digitizing a 5V, 50kHz sinewave

■2- or 8-channel input multiplexer

■0V to 5V analog input range with single 5V power supply

■Operates ratiometrically or with up to 5V voltage reference

■No zero or full scale adjust required

■Analog input protection; 25mA per input min

■Continuous conversion mode

■Low power dissipation; 15mW max

■TTL and CMOS compatible digital inputs and outputs
