DESCRIPTION

The ADC10DL065 is a dual, low power monolithic

CMOS analog-to-digital converter capable of

converting analog input signals into 10-bit digital

words at 65 Megasamples per second (MSPS). This

converter uses a differential, pipeline architecture with

digital error correction and an on-chip sample-and- hold circuit to minimize power consumption while

providing excellent dynamic performance and a 250

MHz Full Power Bandwidth. Operating on a single

+3.3V power supply, the ADC10DL065 achieves 9.8

effective bits at nyquist and consumes just 370 mW

at 65 MSPS, including the reference current. The

Power Down feature reduces power consumption to

36 mW.

The differential inputs provide a full scale differential

input swing equal to 2 times VREF with the possibility

of a single-ended input. Full use of the differential

input is recommended for optimum performance. The

digital outputs from the two ADC's are available on a

single multiplexed 10-bit bus or on separate buses.

Duty cycle stabilization and output data format are

selectable using a quad state function pin. The output

data can be set for offset binary or two's complement.

To ease interfacing to lower voltage systems, the digital output driver power pins of the ADC10DL065

can be connected to a separate supply voltage in the

range of 2.4V to the analog supply voltage. This

device is available in the 64-lead TQFP package and

will operate over the industrial temperature range of

−40°C to +85°C. An evaluation board is available to

ease the evaluation process.
