Single +3.0V Supply Operation

CMOS

analog-to-digital

converter

capable

of

Duty Cycle Stabilizer

providing excellent dynamic performance and a 250

MHz Full Power Bandwidth. Operating on a single

•

Multiplexed Output Mode

+3.0V power supply, the ADC12DL040 achieves 11.1

effective bits at nyquist and consumes just 210 mW

APPLICATIONS

at 40 MSPS, including the reference current. The

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

single multiplexed 12-bit bus or on separate buses.

•

DSP Front Ends

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.

•

Resolution 12 Bits

To ease interfacing to lower voltage systems, the

DNL ±0.3 LSB (typ)

digital output driver power pins of the ADC12DL040

•

can be connected to a separate supply voltage in the

range of 2.4V to the analog supply voltage.

•

Data Latency 7 Clock Cycles

This device is available in the 64-lead TQFP package

and will operate over the industrial temperature range
