2 General Description
The B083000RQC is a radiation hardened, dual, low power, high performance,
CMOS analog-to-digital converter that digitizes signals to 8 bits resolution at
sampling rates up to 3.0 GSPS. Consuming a typical 1.9 Watts at 3GSPS from a
single 1.9 Volt supply. The innovative design of the internal sample-and-hold
amplifier and the self-calibration scheme enable a very flat response of all dynamic
performance. B083000RQC has Extended Control Mode enable user change the
operational parameters for high performance.
