Hello Mattia,
I am sorry for the very long delay. Thank you for sharing the detailed debugging steps, I was able to replicate the same issues you were seeing. The reason the model is doing this, is because the input common-mode voltage of the amplifier…
Part Number: OPA836 Tool/software: 1. First, the operation amplifier circuit test conditions: VDD voltage DC3.6V, S IN input signal suspended in the case.
2. The test waveform at each point is as follows: The waveform at ① is as follows:
②The wavef…
Part Number: OPA836 Tool/software: Hi there!
I want to design an amplifier to boost(amplify) a 0.2mVp-p signal with a 32.768KHz input frequency to around 2Vp-p/32.768KHz. I'm planning to use a multi-stage amplifier because the signal is very low, which…

Part Number: OPA836 Tool/software: Hi everyone,
I'm working with the OPA836 and I need to design a peak detector. I'm using the simplest circuit to simulate it, as shown in the following figures.
Some characteristics of the OPA836 for the peak…
Part Number: OPA836 Other Parts Discussed in Thread: TMUX1101 Tool/software: Hi everyone,
I'm working on a design for a charge-sensitive amplifier with the OPA836 due to its quiescent current, slew rate and bandwidth.
Due to the operating principle…
Part Number: MSP430FR6043 Other Parts Discussed in Thread: TIDM-02003 For the gas metering scheme, I would like to know about the replacement of R74 and R43 in the circuit design of TIDM-02003 MCU050A_Analog-Front-End.SchDoc, as well as the function of…
Part Number: OPA838 Other Parts Discussed in Thread: OPA836 , EVM430-FR6043 , TIDM-02003 , Hello Expert,
We changed from OPA836 to OPA838 according on EVM430-FR6043 to what is specified in the TIDM-02003 reference design.
When we changed OPA838 from OPA836…
Part Number: OPA836 Other Parts Discussed in Thread: OPA838 , , OPA837 Hi team,
My customer is using our OPA836 & OPA838 now.
And they wonder if we have a newer device to recommend.
Requirements:
BW: >200MHz
slew rate:>200V/us
Iq:<1mA
Thanks…
