Part Number: LMH6654 Other Parts Discussed in Thread: LMH6624 , OPA818 Hello friends,
We are looking for a replacement op-amp for LMH6654, because its operating temperature is too low.
The working frequency is 13.6MHz.
The following conditions need to…
Part Number: LMH6654 I'm working on a wide bandwidth signal amplifier. I want to use the LMH6654MF/NOPB as the final output stage. The last amplifier I used had an issue where it worked normally with a 50 ohm DC load, but when the output was AC coupled…
Hello Gozkul,
You could try forcing the common-mode voltage of the ADC to be 2.5V from the same supply as the VCM pin of the LMH6654.
The problem may be the common-mode voltage of the ADC is different from the 2.5V supplied to the LMH6554, which results…
Part Number: LMH6654 Hi,
When the LMH6654 is off (no voltage on V, V-), how much leakage/ off current can be observed on the input pins (IN+/-) when a 1V -3.2V is applied? - the part is configured as unity gain buffer.
Are there protection diodes on the…
Part Number: LMH6654 Other Parts Discussed in Thread: LMH6723 Hello,
I'm currently using the LMH6654 in a prototype Load Transient Circuit for testing high power regulators. The amplifier drives a discrete AB output stage which then switches some load…
Part Number: LMH6654 I'm using the LMH6654 as a comparator for a project and I was wondering how to compensate for input offset in a circuit that uses the op amp in open loop configuration. All the solutions I come across provide only closed loop…
Hello Felix,
Both parts are older and I cannot find the overdrive recovery spec among data I have access to and can locate. My concern is the test was not performed when these devices were characterized, which is why the overdrive recovery specification…
Part Number: LMH6554 Other Parts Discussed in Thread: LMH6703 , LMH32401 , OPA855 , BUF802 , LMH6654 Hello, I am working on a summing circuit for the fast pulses produced by small Silicon Photo Multipliers. I refer here specifically to the ones from OnSemi…
