Product Summary

The AD1671JQ is a monolithic 12-bit, 1.25 MSPS analog-todigital converter with an on-board, high performance sampleand-hold amplifier (SHA) and voltage reference. The AD1671JQ guarantees no missing codes over the full operating temperature range. The combination of a merged high speed bipolar/CMOS process and a novel architecture results in a combination of speed and power consumption far superior to previously available hybrid implementations. Additionally, the greater reliability of monolithic construction offers improved system reliability and lower costs than hybrid designs.
