... OUT nal trims are required to achieve full 12-bit performance over the entire operating temperature range. The MX7847 has a 12-bit parallel data input, whereas the MX7837 operates with a double-buffered 8-bit-bus interface that loads data in two write operations. All logic signals are level triggered and are TTL and CMOS compatible ...
