DESCRIPTION…
The SP7545 is a low–cost, high stability 12–bit CMOS multiplying DAC with on–board data
latches. The SP7545 is constructed using a proprietary low–TCR thin–film process that
requires no laser–trimming to achieve 12–bit performance. With no laser–trimming, inherent
high stability, and a segmented (decoded) DAC architecture, the SP7545 retains its
performance over time and temperature. The SP7545 is available for use in commercial and
industrial temperature ranges. It is available in 20–pin plastic DIP and PLCC packages.
