Test Instrumentation DESCRIPTION
The ADC08DL500 is a dual, low power, high performance, CMOS analog-to-digital converter. The ADC08DL500
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 guaranteed 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 7.2 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.
