DESCRIPTION

The ADC08DL502 is a dual, low power, high

performance, CMOS analog-to-digital converter. The

ADC08DL502 digitizes signals to 8 bits of resolution

at sample rates up to 500 MSPS. Consuming a

typical 1.2 Watts in demultiplex mode at 500 MSPS

from a single 1.9 Volt supply, this device is ensured

to have no missing codes over the full operating temperature range. The unique folding and

interpolating architecture, the fully differential

comparator design, the innovative design of the

internal sample-and-hold amplifier and the calibration

schemes enable a very flat response of all dynamic

parameters beyond Nyquist, producing a high 7.5

Effective Number of Bits (ENOB) with a 125 MHz

input signal and a 500 MHz sample rate while

providing a 10−18 Code Error Rate (C.E.R.)

The converter typically consumes 3.3 mW in the

Power Down Mode and is available in a lead-free 144-lead LQFP and operates over the modified

Industrial (-40°C ≤ TA ≤ +70°C) temperature range.
