APPLICATION INFORMATION
Battery-Powered Applications
The OP90 can be operated on a minimum supply voltage of 1.6 V,
or with dual supplies
±
0.8 V, and draws only 14 pA of supply
current. In many battery-powered circuits, the OP90 can be
continuously operated for thousands of hours before requiring
battery replacement, reducing equipment down time and
operating cost.
High-performance portable equipment and instruments frequently
use lithium cells because of their long shelf-life, light weight, and
high-energy density relative to older primary cells. Most lithium
cells have a nominal output voltage of 3 V and are noted for a
flat discharge characteristic. The low-supply voltage requirement
of the OP90, combined with the flat discharge characteristic of
the lithium cell, indicates that the OP90 can be operated over
the entire useful life of the cell. Figure 1 shows the typical dis-
charge characteristic of a 1Ah lithium cell powering an OP90
which, in turn, is driving full output swing into a 100 k
load.
