When downloading a Manufacturer Part Number (MPN) directly from Altium Manufacturer Part Search, I often see multiple footprint options available for the same component: IPC_A IPC_B IPC_C MFG (...
I am working on a rigid-flex design with two ICs placed on different rigid sections: an MCU on one board an AD5941 on another board The two rigid sections are connected by a flex PCB. This is a 4...
In my circuit, I am using an OPA333 op‑amp to buffer a sensor signal before it goes through a two‑stage RC low‑pass filter (R13–C44 and R14–C45). My simulation shows the overall filter bandwidth i...
I’m using an Infineon TLE4973 current sensor. It has a DCDI pin, which the datasheet describes as a single‑wire, open‑drain, UART‑based interface (master–slave). It specifies logic thresholds (LOW ...
Basic Explanation of my System: The proposed design is a battery-powered wearable device that integrates advanced sensing and power management features. The system operates primarily from a single...
I need to interface a radiation sensor (BG51 by Teviso Sensor Technologies) with TTL output with a CC1352P microcontroller. May I know how to approach this.
The below circuit is take from here. May I know how this circuit maintains the Potential at Reference Electrode and Working Electrode same. Here you can see that the working electrode is connec...
I have 4 very high-impedance analog signals coming from a fine-pitch 100-pin connector to AD8244 buffer inputs. An electrochemical biosensor IC will be mouted on this connector. Its reference elect...
I am using the STM32WBA5MMG module in my design. The reference design is the MB2131 STM32WBA5M M.2 expansion board from ST (schematic), and the external debug connector sheet contains the note: ...
I have an ADC board. This board will communicate with a STM32 develoment board via SPI interface. I am using jumper cables for connecting the ADC SPI lines to ST32 evaluation board. Below is my AD...

I am using AD5941 in my design. The power section of its analog domain (AVDD) is given below. It is obtained from the reference design. You can see the schematics, BOM etc in bottom of this page. ...
I am making a breakout board which contains 4 hall effect sensors from paragraf.The sensor P/N is EGHSX03Q02 .My schematic is given below .Like this 4 sensors placed in the pcb. These sensors are ...
The below image is taken from Analog Devices design note DN1045. what is the use of M1 and M2? What is the use of REF and D1?
I am using OPA859-Q1 in one of my applications. It's supply voltage is 3.3V,single supply operation.I am confused about is output swing when operated from 3.3V supply Is the maximum swing is 2.4V ...
The below schematic is taken from this TI reference design. May I know is there any reason for using 2 MOSFETs here. Hi this link contains the application of the product.This is a Wireless PIR M...
I am using an IR transceiver in my design.This IC is working at 3.3V supply.This IC need not be on always so I decided to give a control to it's shut down pin (Pin no 5,Shutdown Input. Active low)....
I’m designing a 100% flexible PCB (no rigid FR-4 regions in the construction). The board is a wearable strap and we want a 4-layer flex stack. My PCB supplier (Würth “SLIM.flex 4F”) sent me an Alt...
I'm trying to clarify my understanding of the relationship between ADC resolution and ENOB (Effective Number of Bits), particularly when it comes to practical calculations. From what I understand,...
The below image is taken from this refrence design. May I know why the two zero ohm resistors are used.
I am interfacing this gas sensor to the ADC of TI CC1352P. May I know can I directly connect the output of this gas sensor to ADC (I mean after the gas sensor output I will keep an RC circuit with ...
I am using AD5941 for my measurements from different sensors.I will be making a breakout board such that in my board I will be providing pads for connecting the sensors and the output of AD5941 wil...
I am designing discrete IrDA receiver using a TIA and a comparator. My initial circuit is given below. I won't be using a BPF after the TIA as given in the MAX3120 Functional block diagram. The out...
I am using TPS63000 in my design and I need to control PS/SYNC pin using a micro-controller. **The input to the buck boost converter is 3V to 4.3V which is coming from a battery. The microcontrol...
I am trying to simulate a leaky integrator in LTspice using an AD8603 op‑amp. My long‑term goal is to model slow‑changing outputs from MOX gas sensors, but the gas sensor itself is not important fo...
