Hi,
First sorry for the last response. So regarding the state of affairs - I built the housing like Kai suggested (see Fig. 1k) and also got the copper mesh with a transparency of around 80%. Furthermore, I could convince my supervisor to test with…
Other Parts Discussed in Thread: OPA727 I'm using an OPA727 as a non-inverting amp with a gain of 5.6, and I'm seeing excessive offset on the output: about -5 mV, for an input of +0.47 Vdc. The offset is a linear function of the input voltage; it's about…
Other Parts Discussed in Thread: OPA727 Hello,
I'm a bit confused regarding input bias current specifications for the OPA727 op-amp. Referring to the datasheet, the "ELECTRICAL CHARACTERISTICS" specify 85pA typ and 500pA max @ 25C, what common-mode…
Other Parts Discussed in Thread: DAC8831 , DRV135 , OPA727 , OPA2354 Hi
i need the following information. Please let me know.
1) Power dissipation of OPA2354, DAC8831, OPA727, DRV135 IC’s.
2) Current requirement from +5V and -5V for OPA2354, DAC8831…
Part Number: OPA365 Other Parts Discussed in Thread: OPA727 , OPA863A , OPA835 , OPA837 Hello,
I’m looking for a precision op-amp recommendation that can be used as an error amplifier (supply = 12 V nominal) and whose output becomes high-impedance …
Other Parts Discussed in Thread: OPA727 , THS4631 , OPA656 , OPA2323 Is there a way to estimate how well this configuration works on a single supply (preferably 3V)? I'm looking for a sub $1 solution, is there a recommendation for a lower cost, general…
Hi user6350528 ,
Clemens, Thanks for pointing it out! I overlooked the input front end.
If the pin5 is capacitive coupled to the non-inverting node, you would need to have place a high pass filter instead, or connect the input stage posted by Clemens…
Part Number: OPA196 Other Parts Discussed in Thread: OPA727 , , OPA376 , OPA192 , OPA728 , TLV376 , OPA197 , OPA191 Dear Specialists,
I’m a FAE of distributor of Fuji Electronics in Japan.
I am interested in e-trim Opeamps.
I’d like to know more…
Ok, I got this working a lot better,
1. better diode model with less capacitance and leakage
2. The TINA library model for the OPA656 had a high input leakage, the one on the TI website fixed that, holding now to within 2%
This is testing with a…
