2. General Description
The B08D1500RH is a dual, low power, high performance, CMOS
analog-to-digital converter that digitizes signals to 8 bits resolution at sampling rates
up to 1.6 GSPS. Consuming a typical 1.9 Watts at 1.5 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. B08D1500RH has Extended Control Mode enable user change the
operational parameters for high performance.
