Hi Ishan,
Thank you for clarifying, that should be where the saturation issue is coming from when testing the device and changing the offset. The left pad should be set to mid-supply (1.65V) when inputting a signal with the same offset of 1.65V. This…
Part Number: LMP7718 Other Parts Discussed in Thread: OPA320 , LMP7717 I need something close to a 1 Mhz TIA for interfacing to a photodiode. It has to work indoors and outdoors, so I'm looking at DC coupled, but including an additional op amp that will…
Part Number: LMP7718 Other Parts Discussed in Thread: TINA-TI Hi everybody, I am currently designing a high gain transimpedance amplifier to amplify the signal of a pyroelectric sensor. Already read stuff like tidu535. I chose the LMP7718 mainly because…
Part Number: LMP7721 Other Parts Discussed in Thread: TINA-TI , LMP7718 I could find some model like TINA spice model for this LMP7721, but I could not find anything compatible with HSPICE.
How can I find HSPICE compatible model (subcircuit) for this LMP7721…
Thank you Michael. I am concerned about the limited slew rate of LMP7718; if I'm targeting a 1Vp-p output, the 11.5V/us would limit transitions to 87ns (11.5MHz).
Regarding the VFA, this is interesting. The ADC dev board I'm using has an analog input…
Another way to think about your required BW is how many spectral components of the Input fourier series do you want to pass. The input here is 50kHz, it mainly has odd harmonics, so if you want to pass the first 4 odd harmonics you need have a flat response…
Part Number: THS4631 Other Parts Discussed in Thread: TINA-TI , , OPA320 , LMP7718 , OPA838 Hello,
I connected the DUT to the network analyzer (Agilent 4395A). The configuration is shown below.
The bodeplot of the DUT, connected to the VNA, is shown bel…
Thanks, that is good info.
To create this "50kohm" gain, it is still perplexing how do deal with your voltage source through an R source. Not really a current source, is the voltage unknown or the R unknown, and that is what you are trying measure?…
Yes, this circuit.
I'm looking for a circuit to cancel DC currents in the order of mA and only pass the A/C signals (from pA range to uA range).
Also, a similar circuit I found is here: https://e2e.ti.com/support/amplifiers/f/14/t/725612?tisearch=e2e…
