Part Number: OPA2863 Other Parts Discussed in Thread: LMH6643 , Tool/software: Hi Sir,
My customer use OPA2863 to replace LMH6643 for one year. Application about the circuit is 4 level inverting amp application (using 2 OPA2863). The first input signal…
Part Number: OPA2863 Other Parts Discussed in Thread: LMH6643 , Hi Sir,
Customer want to replace LMH6643 by using OPA2863 due to LT question. They test sample and buy a reel OPA2863 for replacement test but have high failure rate / burn out issue.(Failure…
Part Number: LMH6643 Hi,
I have a question about the status of the LMH6643MM/NOPB.
Q1. Is it okay to consider the LMH6643MM/NOPB to be industrial? Q2. Although it is described as "Catalog" on the Web, is it correct to think that it is equivalent to "Industrial…
Part Number: LMH6643 Hello,
I'm analyzing the worst case output voltage error that could be due to the input bias current of the LMH6643. I believe the offset voltage error should be equal to the bias current flowing into IN- times the negative feedback…
Part Number: LMH6643 Other Parts Discussed in Thread: OPA2830 , OPA2837 , OPA2810 , LMH6619 , LMH6612 Hi,
Currently, I used LMH6643 in my designment. Now, I need a similar device with hige operating temperature, -40 to +125. Could you help me to recommend…
Part Number: LMH6643 Other Parts Discussed in Thread: STRIKE Hello everyone, and happy new year!
So, in relation to this topic, I would like to make more or less the following schematic same ESD protection circuit (TVS + Ferrite Bead + Schottky diodes…
Part Number: LMH6643 Dear TI Colleague:
My customer had found a test failure on LM6643: With the signal source input of PIN5 +, the Pin7 output shall be amplified to 2X according the following customer circuit, but actually, it is a failure by a high level…
Part Number: LMH6643
Hi
LMH6643 datasheet was changed from P-ver to Q-ver as below.
What is meaning AT TEMPERATURE EXTREMES? Total temperature range -40C to +85C? or only -40C and +85C?
I'm confusing, because, it was deleted "at Tj=25C" on the P…
Part Number: LMH6643 Hello,
I am simulating expected power dissipation over the LMH6643 in LTSPICE. The datasheet for the LMH664x series indicates how to calculate maximum allowable power dissipation. The LMH6643 has two channels. I am wondering: is…
Part Number: LMH6643 Other Parts Discussed in Thread: OPA810 , OPA2810 Hi
My customer is evaluating LMH6643 with voltage follower circuit.
They found the issue that the output voltage is higher 200mV than input voltage.
V+=+12V, V-=GND
Could you please give…
