This converter uses a differential, pipeline architecture with • Outputs 2.4V to 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 and a 600 MHz Full Power Bandwidth. Operating on a single • Pin Compatible with ADC12DL040, +3.3V power supply, the ADC12DL080 achieves 11.0 ADC12DL065, ADC12DL066 effective bits at Nyquist and consumes just 447mW at 80 MSPS. The Power Down feature reduces power APPLICATIONS consumption to 50 mW. • Instrumentation The differential inputs provide a full scale differential • Communications Receivers input swing equal to 2 times VREF with the possibility • Sonar/Radar of a single-ended input. Full use of 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 KEY SPECIFICATIONS binary or two's complement. • Resolution: 12 Bits To ease interfacing to lower voltage systems, the • Max Conversion Rate: 80 MSPS digital output driver power pins of the ADC12DL080 • DNL: ±0.4 LSB (typ) can be connected to a separate supply voltage in the range of 2.4V to the analog supply voltage. This • SNR (fIN=40MHz): 69 dB (typ) device is available in the 64-lead TQFP package and • SNR (fIN=200MHz): 67 dB(typ) will operate over the industrial temperature range of • SFDR (fIN=40MHz): 82 dB (typ) −40°C to +85°C. An evaluation board is available to ease the evaluation process. • SFDR (fIN=200MHz): 81 dB (typ) • Power Consumption – Operating: 447 mW (typ) – Power Down Mode: 50 mW (typ) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
