The ADC08500 is a low power, high performance CMOS analog-to-digital converter that
digitizes signals to 8 bits resolution at sampling rates up to 500 MSPS. Consuming a typical 0.8
Watts 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 self-calibration scheme enable a very flat response of all dynamic parameters
beyond Nyquist, producing a high 7.5 ENOB with a 250 MHz input signal and a 500 MHz sample rate
while providing a 10-18 B.E.R. Output formatting is offset binary and
the LVDS digital outputs are compatible with IEEE 1596.3-1996, with the exception of an adjustable
common mode voltage between 0.8V and 1.2V.
The converter has a 1:2 demultiplexer that feeds two LVDS buses and reduces the output
data rate on each bus to half the sampling rate.
The converter typically consumes less than 3.5 mW in the Power Down Mode and is available
in a 128-lead, thermally enhanced exposed pad HLQFP and operates over the Industrial (-40°C ≤
TA ≤ +85°C) temperature range.
