Other Parts Discussed in Thread: THS3062 , TINA-TI I have a printed circuit board (PCB) with the following 3 stage amplifier circuit:
The circuit appears to be performing as expected at DC for a wide range of Vbias values from 0 to 1V (and nothing…
Hello Jorge,
I'm not encountering any issues with the THS3062 SPICE model. In fact, I've confirmed that there are no differences between the model we provide for the THS3061 & THS3062.
In regards to the difference between our TINA & Pspice models…
Part Number: OPA859-Q1 Other Parts Discussed in Thread: THS3062 Hi team,
What are "Common-mode input capacitance" and "Differential input capacitance"? Do you have equivalent circuit model for explaining them?
Transimpedance amplifier looks low input…
Part Number: THS3061 Other Parts Discussed in Thread: THS3062 Hello Team,
Is there a dual alternative to ther THS3061DGNRG4 amp? I see there is the THS3062 but its marked for NRND so im hoping there is another amplifier family that i can consider…
Part Number: THS3092 Other Parts Discussed in Thread: THS3217 , THS3491 , THS3062 Hi,
We are using THS3092 op-amp part in our design as inverting amplifier configuration.
Attached schematics shows op-amp configuration used in design.
Input…
Hello Hasan,
Actually the load shall not be low, it is expected to be at least 10k. But the output shall be connected to the load via a 1m 50Ohm or 75Ohm coax cable.
I attach the circuit and the simulations of the parts.
I would appreciate if…
Hi Colin,
I apologize for the delay; I had to order an EVM. It appears that both parts' CMRRs follow the lower rating, currently designated on the datasheet as THS3061. The curve for THS3062 should be discarded. I will notify the higher-ups and begin…
Part Number: THS3061 Other Parts Discussed in Thread: THS3062 , , OPA695
I'm looking at using the THS3061 op-amp (and by extension, possibly the THS3062 op-amp) as part of a simple circuit to add and subtract voltages. These voltages are small-signal…
Hello,
Welcome to E2E and thank you for your query. I couldn't see the attachments. Could you please upload them again. Note that the slew rate will be limited by the slowest component on the path. Hence, you need to remove OPA2277 and use a high slew…
Hi Yatao,
Sorry for the delay in reply.
To answer your questions:
1. The large capacitance drive of a high speed op-amp primarily depends upon the stability and slew rate (V/us) of the op-amp. In Fig 1 you posted, it says that the THS3062 certainly…
