Part Number: THS3491 Hello, I am currently debugging a board using the THS3491. The circuit was designed as an inverting amplifier with a gain of -1. The feedback resistor is 681ohm, and the input resistor is also 681ohm. The intended operation is to…
Part Number: THS3491 Other Parts Discussed in Thread: THS3091 , We compared the THS3491 with THS3091 (latest die revision) and can not see any differences. Exactly the same board types for both.
We checked amplitudes with frequency-sweeps and step responses…
Part Number: THS3491 Tool/software: What conditions must you place this amplifier to cause it to burn up?
The current draw on the positive and negative rail seem to draw too much current, it causes my Trace lines to burn up. Any idea what condition…
Part Number: THS3491 Other Parts Discussed in Thread: LMH5401 , THS3217 , Hello TI Team,
I am currently evaluating the performance of an analog signal chain on a custom PCB and I am observing unexpected harmonic distortion at the power amplification…
Part Number: THS3491 Other Parts Discussed in Thread: DAC3482 , THS3217 Dear Technical Support Team,
How do I extimate the gain such as G=8 for d Noninverting amp?
THS3491 is current feedback, so resistor value is important.
I use RF=576ohm and…
Part Number: THS3491 Tool/software: Hi i see on your THS3491 datasheet you have recommended values at different gain settings for Rf for optimal gain/phase margin. My question are these values entirely based on simulation or do you measure them on the…
Part Number: THS3491 Tool/software:
We are planning to use the THS3491 in our upcoming design. However, due to space constraints on our PCB, we are exploring options for dual and quad channel drivers with similar specifications.
Could you kindly suggest…
Part Number: THS3491 Other Parts Discussed in Thread: TINA-TI , I am sending this request because I cannot post a question to E2E. When I push a "Ask a new question" button in E2E, the page is moved to this "Contact support" page. I have posted many questions…
Part Number: THS3491 Other Parts Discussed in Thread: TINA-TI , THS3217 Hi Team,
I am planning to use the THS3491 for a difference amplifier and transimpedance amplifier (TIA) application. Since my design requires high slew rate and wide bandwidth,…
Part Number: THS3491 Tool/software: In the datasheet there is a ambiguity about the maximum output current drive capability of the THS3491 amplifier.
In "Section 1: Features" it is mentioned that "Linear output current: ±420 mA (typical)" while in …
