9.2.2 Slew Rate Limit for Input Protection

In control systems for valves or motors, abrupt changes in voltages or currents can cause mechanical damages.

By controlling the slew rate of the command voltages into the drive circuits, the load voltages ramps up and down

at a safe rate. For symmetrical slew-rate applications (positive slew rate equals negative slew rate), one

additional op amp provides slew-rate control for a given analog gain stage. The unique input protection and high

output current and slew rate of the OPAx192 make the device an optimal amplifier to achieve slew rate control

for both dual- and single-supply systems.Figure 68 shows the OPA192 in a slew-rate limit design.
