Overview
Specification
Digital input bits: 8 bits
Conversion speed (fCLK): 1GHz
Architecture:
- 4-4 partially segmented current-steering architecture
- Use input data
- Use 1st level and 2nd level F/Fs
- Use R-2R ladder for binary weighted current sources
Digital input: single-ended inputs (DIN<7> ~ DIN<0>)
Analog output: differential outputs (AOUTP, AOUTN)
Output swing: differential 800mVp-p @50Ω load
Power supply: 3.3V for both analog and digital powers
Process: 0.35μm CMOS Technology
