Hi Sir,
Thank you for the suggestions. OPA2172 and TLV2172 looks appropriate.
I wanted to select dual op-Amps for the output feedback error amplifiers /compensation etc ito be used for 300KHz /500KHz or higher DC DC converters with -55C to +125C…
Hi Jerry,
Based on the requirements you've provided, take a look at the OPA172. It can support up to 36V on a single supply, has more than enough bandwidth for your use and low offset voltage of +/-0.2mV.
Let me know if that will meet your needs…

Hi all Would you mind if we ask TLV172? Could you refer to the file "20171217_TLV2172.pdf"? 2705.20171217_TLV2172.pdf 20171218_TLV172.TSC Our customer…
Mike,
Are you sure the first amp is working well? For a robust design, the input pin voltages should be greater than 4V. I'm not sure you have that now.
The output is emitter follower as seen in section 8.2 "Functional block diagram" in the TL082…
Hi Gunter,
Are you using the device in an audio application? If so, consider the OPA4172 or TLV4172 devices. They are recent CMOS devices with good specs and nice audio performance/sound. The input common-mode ranges are different between these devices…
Hello,
Here's a link to a good design guide for non-inverting amplifier circuits. The LMC662 is a good amp but there are much newer alternatives which perform better for lower costs.
For +1.8V - 5.5V supplies look at the TLV9002 (1MHz) or TLV9062…

Dear Team,
We are looking into the below part - LMV358Q1MAXNOPB
Can this part handle +/-5V dual power…
Part Number: UCC28740
Hi, I am using UCC28740 for 24W LED driver application which is using DCM flyback converter in peak current mode control at primary side. please find the specifications below: Input voltage : 85V rms to 264 V rms : 120V DC to 374…
