OPA365: Positive single supply with negative output range

Nam, Dino

Part Number: OPA365
Other Parts Discussed in Thread: LM7705, LM27762

Dear team,

I found TI reference design, Single supply Op Amp with True Drive to GND. but Is there any TI solution not only cover true GND but also negative range with positive single supply? (+15V Single-Supply, Dual Op Amp with ±10V Output Range like maxim MAX44267)?

Thank you.

Hi Nam,

I don't think we have a High Speed Amplifier with integrated charge pump that allows single-supply +15V operation and could generate +/-10V output range. Did you check with the Precision Amplifiers team on this as to whether they have a suitable equivalent?

Best Regards,
Rohit

Hi Dino,

I have not been able to find a device that integrates a negative charge pump like the MAX44267. We do have negative charge pump ICs, such as the LM7705 or the LM27762, but nothing that integrates this with an op amp.
