The ADC08D1520 is a dual, low power, high performance
CMOS analog-to-digital converter that builds upon the
ADC08D1500 platform. The ADC08D1520 digitizes signals to
8 bits of resolution at sample rates up to 1.7 GSPS. It has
expanded features compared to the ADC08D1500, which include
a test pattern output for system debug, a clock phase
adjust, and selectable output demultiplexer modes. Consuming
a typical 1.6 Watts in Non-Demultiplex Mode at 1.0 GSPS
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 self-calibration
scheme enable a very flat response of all dynamic parameters
beyond Nyquist, producing a high 7.4 Effective Number of Bits
(ENOB) with a 748 MHz input signal and a 1.5 GHz sample
rate while providing a 10-18 Code Error Rate (C.E.R.) Output
formatting is offset binary and the Low Voltage Differential
Signaling (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.
