Alex, I've just tested the circuit replacing OPA4188 for the OPA4170. It performed as expected, without any distortion. I tested it with input frequencies as high as 40 kHz (4 times higher than the actual input maximum) and didn't get any distortion.…
David,
We have several quad op amps with the input common-mode voltage range beyond both rails; please see take a look at OPA4191, OPA4192, OPA4196 and OPA4197.
Hi Zed
1. What is different between In to V-, Out // In to V- // In, Out
In, Out means Rail-to-Rail Input/Output or RRIO = In, Out, example is OPA4991 in the table
In to V-, Out means the input Vcm can be as low was V- only, and output is Rail…
Hi Charles,
I know what is going on. You are applying the OPA4188 amplifier section as a comparator, with a 2.21 V reference voltage applied to the inverting input. When you drive the non-inverting input to the 1.45 V level you forward bias one of the…
Part Number: OPA4188 Other Parts Discussed in Thread: INA149 , OPA4191 , OPA4192 , TINA-TI Dears,
I want to sampling the BUS voltage, the total voltage is about 800V(DC). I have adjusted to about 50V through precision resistance voltage divider, and…
And, I think I finished scanning the TI product trees for post 2015 <50MHz Introductions - omg, this is quite impressive, lot of work here to fill in the parametric fields, but this is the list I came up with the slightly modified descriptions - this…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
