ML2281, ML2282*,

ML2284#, ML2288#

Serial I/O 8-Bit A/D Converters with

Multiplexer Options

GENERAL DESCRIPTION

The ML2281 family are 8-bit successive approximation

A/D converters with serial I/O and configurable input

multiplexers with up to 8 input channels.

All errors of the sample-and-hold, incorporated on the

ML2281 family are accounted for in the analog-to-digital

converters accuracy specification.

The voltage reference can be externally set to any value

between GND and V

, thus allowing a full conversion

over a relatively small voltage span if desired.

The ML2281 family is an enhanced double polysilicon

CMOS pin compatible second source for the ADC0831,

ADC0832, ADC0834, and ADC0838 A/D converters. The

ML2281 series enhancements are faster conversion time,

true sample-and-hold function, superior power supply

rejection, improved AC common mode rejection, faster

digital timing, and lower power dissipation. All parameters

are guaranteed over temperature with a power supply

voltage of 5V ±10%.

FEATURES

Conversion time: 6µs

Total unadjusted error: ±1/2LSB or ±1LSB

Sample-and-hold: 375ns acquisition

2, 4 or 8-input multiplexer options

0 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

ML2281 capable of digitizing a 5V, 40kHz sine wave

Low power: 12.5mW MAX

Superior pin compatible replacement for ADC0831,

ADC0832, ADC0834, and ADC0838

Analog input protection: 25mA (min) per input

Now in 8-Pin SOIC Package (ML2281, ML2282)
