Part Number: LMH6644 Other Parts Discussed in Thread: OPA4863 Hai,
I'm looking for spice model for LMH6644, but i didn't find anywhere. Suggest me where can found the spice model.
Can anyone provide short and brief introduction about LMH6644 like…
Part Number: LMH6644 Dear colleague,
A customer use LMH6644 to shift Serial TX and RX signal. The schematic is below，RO&RI is RX signal，CO&CI is TX signal. Vsupply+ - Vsupply- = 5.5V.
RO&RI test result:
RO is yellow curve and LMH6644 D channel…
Other Parts Discussed in Thread: LMH6644 I have a circuit using an LMH6644 as a 4-way unity buffer which is marginal in terms of input common mode range. The positive power supply to the LMH6644 has a minimum theoretical value of 3.26 V, and the input to…
Other Parts Discussed in Thread: LMH6644 , LMH6643 Hello
To whom it may be concern
Our customer considering to use LMH6644.
One concern is the spec of Vos(max) and TC_Vos within -5 to 55 deg temp range.
Could you provide the value or how to calculate(or…
Other Parts Discussed in Thread: LMH6644 Hi,
I'd like to ask how LMH6644 amp can be used as 2.77sec delay output.
when I tried to re-build the circuit with sig-gen as material, it never shows output(delay) as expected.
please refer to the attachment…
Other Parts Discussed in Thread: LMH6644 , LMH6618 Hello
I would like to know the value of the CMVR of LMH6644 as below specification.
The specification shows CMVR which are Min Typ Max in yellow color. The values are scattered from Min:1.8, 1.6, Typ: …
Part Number: LM358 Other Parts Discussed in Thread: TINA-TI , , LMH6644 , Tool/software: TINA-TI or Spice Models Hi team
I ran the LM358 simulation via TINA as an attach file.
Final output voltage is less than 100mV.
In the actual circuit, about 1.1V is…
Both traces have GND level on the lowest horizontal division marker; trace 1 (yellow) is at 500 mV/div.
Yes, they come close enough to positive supply rail (3.3V), so if I can trust the data sheet, an LMH6644 should go a bit higher than 3V (...) and recover…
Hi Samir and Emkay,
I have used TINA-TI to measure the LMH6644 phase margin with a heavy cap load. For this to work, I had to estimate the device output impedance (R + L) that would cause excess phase shift with a heavy cap load. I did not spend too much…
