ML2281 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 VCC, 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%.
