Part Number: LMH6643 One of our customer use LMH6643MA to build a three-point capacitance oscillation circuit, with ceramic tiles capacitance C, L with coil (used to detect metal);
The question is:
1. Some machines can't afford to vibration or unstable…

Hello,
I am designing ESD protection for the LMH6643 for an event on the output pin. I would like to know the maximum allowable current into the input output pin during such an event.
The…
Part Number: LMH6643 There is a LMH6643 Capacitance three point oscillation circuit like the picture below (J2 connect ot the inductance coil):
2 Problem :
1. Some of the LMH6643 : Heat it : oscillation, cold state :No oscillation.
2. Frquency of oscillation…
Part Number: LMH6643 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hello,
My client is designing a new sensor front-end circuit with LMH6643 now. I introduced TINA-TI for conducting simulations. He uses parametric simulation…
Part Number: LMH6643 Hi,
I've realised the circuit below with the LMH6643 to buffer a fast Signal (100ns rise time) with 0-5V to drive a coax cable with 75Ohm terminantion.
No I've measured at the circuit and realised that the output signal after the…
Hi Ore
Thank you for getting back to me
Responding to your specifics:
- SOIC-8 [D0008A] Package : primarily for ease and availability
- output cuttent negligible : one stage feeds the next thro ~47k, the second stage feeds a 74LVC1G17GW thro 10k
- slew…
Hello Paul,
Are you still observing the output rise time & delay time extensions during high temperature? I can assist with recommending a different package type or high-speed op-amp. I did notice the use of the LMH6643 IC on the schematic you sent…
Other Parts Discussed in Thread: LMH6643 , TINA-TI , OPA2301 , OPA2300 Hi
The customer evaluate LMH6643 as Peak Hold detection circuit. But it does not work as we thought.
(We simulated it by TINA-TI before evaluation. It did work.)
Please see below circuit…
Other Parts Discussed in Thread: LMH6643 , OPA2830 , OPA2301 , LMH6619 , TINA-TI , VCA821 I've designed and built a 2-Amp instrumentation amplifier like the one below:
My primary candidates for the amplifier are the LMH6643, OPA2830, and OPA2301. Currently…
