1FEATURES DESCRIPTIONThe ADC12DL080isa dual, low power monolithic
Single +3.3V Supply Operation CMOS analog-to-digital converter capable of
• Internal Sample-and-Hold converting analog input signals into 12-bit digital
Internalor External Reference wordsat 80 Megasamples per second (MSPS). This
converter usesa differential, pipeline architecture with
• Outputs 2.4Vto 3.6V Compatible digital error correction and an on-chip sample-and-
• Power Down Mode hold circuit to minimize power consumption while
• Duty Cycle Stabilizer providing excellent dynamic performance anda 600
MHz Full Power Bandwidth. Operating ona single
• Pin Compatible with ADC12DL040, +3.3V power supply, the ADC12DL080 achieves 11.0
ADC12DL065, ADC12DL066 effective bitsat Nyquist and consumes just 447mWat MSPS. The Power Down feature reduces power
APPLICATIONS consumptionto50 mW.
Instrumentation The differential inputs providea full scale differential
• Communications Receivers input swing equalto2 times VREF with the possibility
Sonar/Radar ofa single-ended input. Full useof the differential
input is recommended for optimum performance.
• xDSL, Cable Modems Duty cycle stabilization and output data format are
selectable. The output data can be set for offset
