00:00Best SOP8 op-amps under 6 bucks. I dug through sold counts, ratings, and real listings so you
00:06don't have to, and honestly, a few of these are stupid cheap for what you get. First up,
00:11the OPA228U, 5 pieces for $2.62. That's about 50 cents a chip for a precision,
00:19low-noise single op-amp in a genuine SOP8 package. 4.6 stars, nearly 5,000 sold.
00:26If you're doing sensor front ends or anything where noise floor actually matters,
00:30this is your chip, and at this price you can afford to blow one up learning.
00:34Next, the LF351D, 10 pieces for $4.21. JFET input single op-amp, the classic high-impedance
00:43workhorse. 4.7 stars, over 4,700 sold. Great for guitar pedals, buffers, anything with a
00:51high-impedance source that a bipolar input would load down. 42 cents apart and you basically never
00:57run out. Then the TL082CDR'd 10 for $1.57. Yeah, you heard that right? 16 cents a chip for a
01:08dual
01:08JFET op-amp, and it's sitting at a perfect 5-star rating with 4,000 sold. This is the one
01:14you keep
01:14in the drawer forever. Audio, filters, general-purpose analog, it just works, and it's cheap enough that you
01:21don't think twice about using one. Now the TP226210 for $4.90, or 50 pieces if you want bulk.
01:30Low-power, SOIC 8, new and original. 4.9 stars, 3,390 sold. This is the one for battery-powered
01:40builds, low-quiescent current, dual-channel, and the rating says people aren't getting duds.
01:45Worth the extra money over the bargain bin if your design actually cares about current draw.
01:50And the TLV2372IDR 10 for $4.48. Instrument precision op-amp, dual, rail-to-rail-ish behavior,
02:00perfect 5 stars. 45 cents each. If you're conditioning signals from a load cell, thermocouple,
02:07or any small sensor, this is the part where cheap stops being the priority and accuracy starts.
02:13Best-rated chip on this list. Links to every single one are in the description below,
02:18along with current prices, they move, so check before you buy.
