ADC12DL065

Dual 12-Bit, 65 MSPS, 3.3V, 360mW A/D Converter

General Description

Features

n Single +3.3V supply operation

n Internal sample-and-hold

n Internal reference

The ADC12DL065 is a dual, low power monolithic CMOS

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

put signals into 12-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 ADC12DL065 achieves 11.0 effective bits

at nyquist and consumes just 360 mW at 65 MSPS, including

the reference current. The Power Down feature reduces

power consumption to 36 mW.

n Outputs 2.4V to 3.6V compatible

The differential inputs provide a full scale differential input

swing equal to 2 times V_REFwith 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.

n DSP Front Ends

To ease interfacing to lower voltage systems, the digital

output driver power pins of the ADC12DL065 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 evaluation process.
