ADC12DL040

Dual 12-Bit, 40 MSPS, 3V, 210mW A/D Converter

General Description

The ADC12DL040 is a dual, low power monolithic CMOS

analog-to-digital converter capable of converting analog in-

put signals into 12-bit digital words at 40 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 +3.0V

power supply, the ADC12DL040 achieves 11.1 effective bits

at nyquist and consumes just 210 mW at 40 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 V

REF with the possibility of a single-

ended input. Full use of the differential input is recom-

mended for optimum performance. The digital outputs from

the two ADC’s are available on a single multiplexed 12-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 comple-

ment.

To ease interfacing to lower voltage systems, the digital

output driver power pins of the ADC12DL040 can be con-

nected 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 evalua-

tion process.
