Description
The HI20203 is an 8-bit, 160MHz ultra high speed D/A con-
verter. The converter is based on an R2R switched current
source architecture that includes an input data register with
a complement feature and is Emitter Coupled Logic (ECL)
compatible.
The HI20203 is an 8-bit accurate D/A with a linearity error of
0.5 LSB.
For 10-bit resolution, please refer to the HI20201 data sheet.
