Part Number: OPA2140 Hello,
We have a design where the minimum consumption on both amplifier power supplies (+/-12V) is a key design driver.
- What is the minimum quiescent current per amplifier to be considered ? At room temperature and in the whole…
Part Number: OPA2140 Other Parts Discussed in Thread: OPA2192 Hello,
I have some questions regarding OPA2140 used to
- buffer a 5V precision voltage reference to increase the load current
- invert the same 5V precision voltage reference to create a -5V…
Part Number: OPA2210 Other Parts Discussed in Thread: OPA2140 , INA851 , OPA2828 , PGA855 , OPA140 Tool/software: The previous thread was locked.
I stacked another resistor network on OPA2140 feedback, and the CMRR improved. The unit is in uV/V
While this…
Part Number: OPA2210 Other Parts Discussed in Thread: OPA2140 , INA849 , INA851 , PGA855 Tool/software: Hi TI,
I am using OPA2210 as a discrete instrumentation front end as such:
I am evaluating the circuit CMRR, and based on my result, OPA2210 gives a…
Part Number: OPA2140 Other Parts Discussed in Thread: OPA145 , , OPA2145 Hi,all
In order to save one supply, I plan to use the +5V and the -15V which are available,as the supply of opa2140/opa145. So i want to know whether there are some problems with this…
Part Number: OPA2140 Tool/software: WEBENCH® Design Tools Hi,
I'm using Filter Design Tool to design an active low-pass filter which is also the ADC driver. The gain should be 0.25 to accommodate ADC's input range. However, I found that the smallest allowable…
Hi Vijay,
I'm not sure that you need 15V/μs slew rate... The 330pF capacitor (C47) creates a low pass filter with the 2.49MΩ series input resistance resulting in a input signal bandwidth of less than 200Hz.
Typically, the slew rate requi…
Part Number: OPA2140 In an EEG application, two 2140 are used as instrumentation amplifier before subtracted.
According the IEC 60601-1-2, this application shall be RF stressed i.e. be immune from 150 kHz upu to 3 GHz at 10 volts i.e. 10 V/m
As the EEG…
Part Number: OPA1642 Other Parts Discussed in Thread: OPA2140 , OPA827 , , OPA140 OPA827, OPA2140 & OPA1642 source impedance and distortion issue. Dear Sir/Madam, While reviewing the datasheet OPA1642, by chance, I learnt the specifications in chapter…
Part Number: OPA2140 We have realized a TIA card using OPA2140. We did the frequency response of the card. How can I characterize (practically) the circuit with respect to Noise. I mean I need to get the parameters like thermal noise floor, corner frequency…
