TECHNICAL NOTES
Reference ladder floating with respect referenced anywhere within specified limits. modulation reference voltage also utilized; contact DATEL further information. Clock Pulse Width improve performance when input signals exceed Nyquist bandwidths, clock duty cycle adjusted that portion (sample mode) clock pulse 15nSec wide. Reducing sampling time period minimizes amount input voltage slews prevents comparators from saturating. full-scale input produces data outputs. DATEL uses conservative definitions when specifying Intergal Linearity (end-point) Differential Linearity (code transition). specifications using less conservative definition have also been provided comparative specification products specified this way. process that used fabricate ADC-208A eliminates latchup phenomena that plagued CMOS devices past. These converters require external protection diodes. clock rates less than 100kHz, there some degradation offset differential nonlinearity. Performance improved increasing clock duty cycle (decreasing time spent sample mode).
