8.3.4 Output Drive

The OPAx354 output stage supplies a continuous output current of ±100 mA and yet provide approximately
2.7 V of output swing on a 5-V supply, as shown in Figure 30. For maximum reliability, TI does not recommend running a continuous DC current in excess of ±100 mA. See the typical characteristic curves, Output Voltage Swing vs Output Current (Figure 20 and Figure 22). For supplying continuous output currents greater than ±100 mA, the OPAx354 may be operated in parallel, as shown in Figure 31.

The OPAx354 provides peak currents up to 200 mA, which corresponds to the typical short-circuit current. Therefore, an on-chip thermal shutdown circuit is provided to protect the OPAx354 from dangerously high junction temperatures. At 160°C, the protection circuit shuts down the amplifier. Normal operation resumes when the junction temperature cools to below 140°C.
