Part Number: OPA4377 Other Parts Discussed in Thread: TLV9054 Hi,
We need an a low cost alternative of OPA4377 that will used in Solar Inverter signal conditioning circuits.
Best Regards
Part Number: OPA4387 Other Parts Discussed in Thread: OPA4377 Hi team,
I was comparing the spec of OPA4377 and OPA4387. I believe OPA4387 is next generation model of OPA4377, but there are huge differences in offset characteristics shown below.

Part Number: OPA4377 Hi Team,
Customer is now using OPA4377 for below reference design for a BT speaker project. However, OPA4377 is quite expensive. Do we have cheaper solution that is P2P with OPA4377 and is able to meet below reference design requirement…

Hi
It is mentioned on the datasheet that the input terminal has a clamp-diode.
So that ,the absolute maximum rating of the input terminal is defined as bellow.

Part Number: PMP9774 Other Parts Discussed in Thread: OPA4377
When we input sinusoidal signal (such as 1KHz signal) on PMP9774 EVM board, we found that the negative half cycle of the signal was not flipped but cut off, so that the part of the cut signal…
Part Number: PMP9774 Other Parts Discussed in Thread: TPS61088 , , OPA4377 Hello,
Could you help two questions below?
1. May I ask for more description on the generation of the envelop signal? I'm not sure why the two stage of buffers are required…
Thanks Helen. I'd like to minimize complexity and keep BOM cost as low as possible (the OPA4377 are $3.98ea in Aus). Is it possible to remove the amplifier and connect the output of the MCU DAC directly to the gate of Q1? What are the risks of a direct…
Hello Kensuke,
There are no R-R input LMV devices with EMI filters. There are currently no plans to create any new R-R input, EMI protected LMV devices (at least in SVA).
See the OPA4377 - a Quad R-R input with EMI protection - at about the same price…
