OPA2674: Output current capability

Part Number: OPA2674

To whom it may concern,

I have these questions:

1) Are the specs listed on the data sheet for 1 of the 2 op-amps or 2 op-amps working together?

2) If I want to drive a 10ohm Rload with 0-5V swing, can I use +6V as V+ and -2.5V as V-?

3) If the answer to the first question is 2 op-amps working together, can you really put two op-amps in parallel for more output current?

Thank you.

Hello Weiyu,

1) One of the two opamps, unless "Both Channels" is stated in the test conditions.
2) Yes, as long as the total supply voltage does not exceed the maximum range.
3) This blog post delves into using op-amps in parallel to increase current drive: e2e.ti.com/.../how-to-reduce-distortion-in-high-voltage-high-frequency-signal-generation-for-awgs

Hope this helps!
