7.3.6 Output Drive

The OPA357 output stage can supply a continuous output current of ±100 mA and still provide approximately 2.7 V of output swing on a 5-V supply, as shown in Figure 33. For maximum reliability, TI recommends running a continuous DC current in excess of ±100 mA; see Figure 21 and Figure 23. For supplying continuous output currents greater than ±100 mA, the OPA357 can be operated in parallel as shown in Figure 34.

The OPA357 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 OPA357 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.
