Hi Chandra,
Thanks for the additional information. I do recommend an additional ADC driver stage for your circuit. For a 16-bits @1MSPS I recommend OPA388 for its wide (10MHz) bandwidth. OPA388 is a zero-drift, zero-crossover, rail-to-rail input and output…

Hi Stefan,
Both OPA387 (5 MHz) and OPA388 (10 MHz) are MUX-friendly, they both use a similar switching architecture at the front end as OPA189. For lowest noise, OPA388 is the best choice, but for lower power, OPA387 is the best.
Let me know if there…
Part Number: ADS1114 Other Parts Discussed in Thread: OPA387 , I have an ADS1114 receiving an input signal between 0V - 4V, the signal goes through an OPA387 set up as a buffer, just before the A0 input of the ADC i have a low pass filter for 80hz made…
Part Number: OPA182 Other Parts Discussed in Thread: OPA387 , OPA187 , OPA186 Hello, My application requires lowest possible offset drift with + / - 5V Dual Supply. I am checking OPA182 in my design but I see the common mode voltage range is (V–) – 0.1…
Hi Naga,
As Mike implies, you need to provide us some design and accuracy requirements. I do not know what performance specification you are looking for.
As an example, here is a circuit. It is not perfect, but it may be close enough in terms of accuracy…
Part Number: LM4051-N Other Parts Discussed in Thread: OPA387 , , ADS1114 I am level shifting a signal from a scale of -12V to +12V down to 0V to 4V, im using a voltage divider that divides /6 and then i shift the whole signal using the LM4051-N (GRADE…
Part Number: OPA2376-Q1 Other Parts Discussed in Thread: OPA192 , OPA2376 , OPA388-Q1 , OPA387 Hi Expert，
Do we have a Vos range of TA = –40°C to +125°C?

Other Parts Discussed in Thread: OPA387 , OPA2387 Hello,
I am currently working on a circuit that can read the solar reference cell voltage output value. I am using MCP6072 for amplify to STM32F0 microcontroller ADC. I want to change it. Can you suggest me…
Jonathan,
Chopper amplifiers are an excellent choice for low offset, and low offset drift. However, the chopping calibration process generates current transients on the inputs of the amplifier that translate into input offset when large feedback and input…
