TLV2451 Operational Amplifier ( you can use almost every operational amplifier, just remember to check that is rail-to-rail).
22 uF capacitor
3.3 kOhm resistor.

there is no TLV, OPA. it's hard to find..

This is a Texas Instruments part, take a look here https://www.ti.com/product/tlv2451/description?keyMatch=tlv2451&tisearch=Search-EN-Everything

You may even be lucky and get a sample.

It's basically just an op-amp buffer stage. Replace that with another rail-to-rail opamp if you can't find it.

Here's one from Microchip (MCP600x): **broken link removed**
You can get free samples from Microchip depending on where you are. If not, they're really cheap.

If you still want to go with the TLV2451: https://www.digikey.com/product-detail/en/TLV2451CP/296-1889-5-ND/277534
