Description
o ~ ~National ~ ~Semiconductor PRELIMINARY o C,o.O..ADC1080, ADC1280 12 *Bit Successive Approximation o«c AID Converter General .
The ADC1080 and ADC1280 are complete successive approximation analog-to-digital converters that include an internal clock, reference and comparator.
Features
* Completely self-contained with internal reference, clock, and comparator
* High reliability exact replacement for ADC80
* ± 1/2 LSB
Applications
* All digital signals are" fully TTL compatible; output data may be read in both serial and parallel form. The ADC1280 has a maximum linearity of 0.012% of FSR and the ADC1080 has a maximum linearity of 0.048% of FSR. Both grades are specified for use over the - 25°C to
+ 85°C temperature range and b
