Op-Amp Amplifier and Filter Prototype PCB
2 sided FR4 PCB that implements a configurable op-amp circuit for single SOT23-5 amplifiers and 0805 passive components and 0.1inch grid pins.
So I've designed a generic amplifier/filter board for surface mount components that can be fitted to a 0.1inch grid compatible with Arduino or Raspberry Pi breakout boards. The circuit can be configured as an inverting, non-inverting or differential amplifier; filter capacitors can be added or set up as a Sallen-Key filter. The amplifier can be powered from single or dual rail supplies.
The Op-Amp U1 has a SOT23-5 footprint that is compatible with many single op-amps such as LM7321, LMC7101, OPA348, OPA192, TLV271, MCP6001, MCP601, MCP6L71, MCP6L01, AD8613, LT6003 etc.
LM7321 is a favourite of mine as it can drive long wires without instability making it suitable as a remote buffer for sensors or analog drivers.
I may have some spare PCBs if anyone wants to try out a project; let me know in the comments.
