ADC12DL080

Dual 12-Bit, 80 MSPS, A/D Converter for IF Sampling

General Description

Features

n Single +3.3V supply operation

n Internal sample-and-hold

n Internal or External reference

n Outputs 2.4V to 3.6V compatible

n Power down mode

The ADC12DL080 is a dual, low power monolithic CMOS

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

put signals into 12-bit digital words at 80 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 600

MHz Full Power Bandwidth. Operating on a single +3.3V

power supply, the ADC12DL080 achieves 11.0 effective bits

at Nyquist and consumes just 447mW at 80 MSPS. The

Power Down feature reduces power consumption to 50 mW.

n Duty Cycle Stabilizer

n Pin compatible with ADC12DL040, ADC12DL065,

ADC12DL066

Key Specifications

n Resolution

12 Bits

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. Duty cycle stabilization

and output data format are selectable. The output data can

be set for offset binary or two’s complement.

— Operating

To ease interfacing to lower voltage systems, the digital

output driver power pins of the ADC12DL080 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.
