RES11A: Does Ti have plan to release more Matched Resistor Dividers

Part Number: RES11A

This product is quite good, but ratio 1:10 is not enough, in most current amplifier we need 1:100 or even more,

Is there plan to release more series?

Hello Qingfeng,

As we expand our portfolio of matched resistor pairs, we welcome this type of feedback! (Hopefully others will chime in on this thread as well!)

While we can't speak in detail on a public forum about our future roadmaps, TI is planning to bring a variety of useful ratios and magnitude resistors to market to enable our customers to build more precise signal chains paired with our amplifiers, data converters and microcontrollers.

We'd welcome your thoughts on useful ratios and magnitudes for your current amplifier circuits.

Thanks,
Scott

Scott:

In my case are 100:1, 150:1 and 200: 1， these are typical ratio for current amplifier with resistor shunt)

Scott:

in my case these required ratio is 100:1/200:1; which are typical for current amplifier amplification (with shut resistors).

Hi Qingfeng, thanks for the inputs. It would be good to know the absolute magnitude you find useful as well. e.g. 100:1 being 100k/1kohm or 10k/100ohm, etc.

from noise point of view, 10K/100OHM sounds good...
