ML2280中文资料MICRO-LINEAR数据手册PDF规格书

GENERAL DESCRIPTION

The ML2280 and ML2283 are 8-bit successive approximation A/D converters with serial I/O and configurable input multiplexers with up to 4 input channels.

All errors of the sample-and-hold incorporated on the ML2280 and ML2283 are accounted for in the analog-to-digital converters accuracy specification.

FEATURES

■ Conversion time: 6µs

■ ML2280 capable of digitizing a 5V, 40kHz sine wave

■ Total unadjusted error with external reference: ±1/2LSB or ±1LSB

■ Sample-and-hold: 375ns acquisition

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

■ 2.5V reference provides 0 to 5V analog input range

■ No zero- or full-scale adjust required

■ Low power: 12.5mW MAX

■ Analog input protection: 25mA (min) per input

■ Differential analog voltage inputs (ML2280)

■ Programmable multiplexer with differential or single ended analog inputs (ML2283)

■ 0.3 width 8- or 14-pin DIP, or 8-Pin SOIC (ML2280)

■ Superior pin-compatible replacement for ADC0833
