00:00Okay, so you're building out a signal chain and you need an op amp that actually does its job
00:04without costing a fortune. I went down the rabbit hole and pulled together the five best deals I
00:08could find for operational amplifiers for signal processing, and trust me, some of these prices
00:13are genuinely surprising. First up is the AMC 1100 DUBR20 pack in SOP8. This is an isolated
00:20amplifier, which means it's perfect for shunt-based current sensing and keeping your low-voltage side
00:25safe from high-voltage transients. You're getting 20 of them for $16.46, and with almost 4,800 sold
00:33and a 4.7 rating, people are clearly happy. If you're doing motor control or power monitoring,
00:39this is a no-brainer bulk buy. Next, the 10-piece AMC 1100 DUBR basic isolated amplifier, same chip,
00:47smaller pack, and it drops to $9.01. This is the one I'd grab if you just want to prototype
00:53a couple
00:53of isolated measurement circuits without committing to a full reel. Over 4,200 sold, 4.7 stars,
01:01surface mount SOP8, and honestly, for the price of a sandwich you're getting 10 precision isolated amps.
01:06Then there's the AMC 1200 STUBR and AMC 1100 mix pack, 10 chips for $3.11, and this listing has
01:14a
01:14perfect 5-star rating with over 4,000 sold. These are new original isolation amplifier ICs in SOP8,
01:21and the AMC 1200 series gives you that same isolation with a slightly different input range.
01:26At $0.31 a chip, this is the cheapest way into isolated signal processing I've seen, period.
01:33If you need something through-hole and rock-solid, the ISO 124P and ISO 122P and DIP8 are legendary
01:40precision isolation amplifiers, analog devices, classics that engineers have trusted for decades.
01:45This listing gets you one piece for $5.15, rated 4.7 with 3,500 sold.
01:52These are newer original stock, in stock now, and if you're repairing old gear or building
01:57something that needs a bulletproof isolated front end, this is the one.
02:01And finally, for the high-speed crowd, there's the ADA29 amplifier module with adjustable gain up to
02:07100x, ultra-low input bias current, and precision high-speed amplification.
02:12It's $21.33, which is the priciest on this list, but it's a ready-to-use module,
02:18no soldering tiny-soisy pins, just drop it in.
02:22$3,400 sold at 4.7 stars, and it's in stock, so if you're doing photodiode or fast signal work,
02:28this saves you a ton of layout headaches.
02:30So there you go 5 solid op-amp options for signal processing at every budget,
02:35from $3 to $21.
