Regarding your store's Op-Amp selections

Good day,
I am looking for a single supply op-amp besides the LM324. Is there any which have more stable Vout (lower voltage swing)?

hi,

mayb u will like MCP602 http://cytron.com.my/viewProduct.php?pcode=IC-MCP-602&name=IC%20MCP602

not sure what do u mean by lower voltage swing. i tot voltage swing is controlled by the circuit configuration and the input swing.

people look for Gain BW, PSRR, Gain etc of the op amp.

The LM324 has 4 op-amps inside. If you really need 4 of them then the one recommended by yonghui MCP602 has only 2 inside. You'll need a MCP604 or 2 pcs of MCP602. mcp602 consumes very little current and has a low operating voltage. It can be battery powered.

Another good Rail to Rail op-amp is LMC6084 from National Semi. If you're doing the Flexiforce project, you can get MC34071 from RS Malaysia. It is also a R to R op-amp but I think the designer uses V- supply to let the output swing closer to the ground rail.
