2. General Description
The B08D1000RH 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 1.2 GSPS. Consuming a typical 1.6 Watts at 1 GSPS from a
single 1.9 Volt supply, this device is guaranteed to have no missing codes over the
full operating temperature range. The innovative design of the internal
sample-and-hold amplifier and the self-calibration scheme enable a very flat response
of all dynamic performance. B08D1000RH has Extended Control Mode enable user
change the operational parameters for high performance.
