Part Number: OPA890 Hi team,
Could you give me comment on following customer question?
Q1. Is it correct understanding that the OPA890 won't be damaged when applying up to +/-Vs as the differential input voltage?
The customer couldn't find description…
Part Number: OPA890 HI, In OPA890 datasheet (section Input and ESD protection) it is stated that all device pins are protected with internal ESD protection diodes to the power supplies. I guess it relates not only to the inputs, but to the output as well…
Hello,
In my experience, what is happening here is that when the major bits are flipping the ADC requires a large amount of transient current. I believe the OPA890 is incapable of providing this inrush current which is resulting in the dc error around…
Other Parts Discussed in Thread: OPA890 In OPA890 datasheet,(SBOS369B �MAY 2007�REVISED DECEMBER 2009),the disable time is 7 uS at page 4 (+-5V),but 7ns at page 6(5V). Why so big difference? It seem wrong. The value do not agree with Figure 21 at page…
Other Parts Discussed in Thread: OPA690 , OPA890 I use OPA890 or OPA690 as a unity gain buffer. But the output show a small oscillation.
According the datasheet, I directly connect Output and inverting input in using OPA890 ,and
connect Output and…
Other Parts Discussed in Thread: OPA835 , OPA890 For ADSL2+ application,customer used the OPA835,but in order to get better THD, higher P/S range,they intend to move to OPS890.
Is this is the right/best recomended solution?
Part Number: OPA2890 Other Parts Discussed in Thread: OPA890 , THS3491 , LMH6703 Tool/software: Dear Technical Support Team,
What is the maximum frequency of the OPA890 for square wave?
10MHz seems to operate correctly, however 250MHz (500Mhz) is…
Hi Chance,
I am sorry, but we don't have a similar part in a lower current package. Would it be possible for you to use a lower supply voltage part such as the OPA890 or OPA838 operating at +3V that provides soft-limiting when the output voltage reaches…
Part Number: LM8261 Other Parts Discussed in Thread: OPA890 , OPA690 Hello,
I currently use LM8261 in an improved Howland current pump design. Current pump is supplied by +/-5V sources and is designed to output 100kHz sinusoidal 4mA pk-pk current. It…
hello Adrian, while dated, those are in some ways still the leaders in the +/-5V choices. I did a wide review of VFA topologies related to getting slew enhancement in this article. There were some later parts (OPA890 and OPA2890) and then only in dual…
