00:00LTC 2353 vs LTC 2357, which ADC is better?
00:06So you're hunting for an ADC module, and honestly, the spec sheets for the LTC 2353 vs the LTC 2357
00:13are where most people get stuck. Here's the thing though, what actually matters is what you plug
00:18into your Arduino or ESP32 and what it costs you. I pulled the top-selling analog-to-digital
00:25converter boards on the market, checked the pricing, the channel counts, and the real-world
00:29accuracy, and found the best deals. Let's get into it.
00:34Starting with the most popular option out there, the high-performance 4-channel 16-bit ADS-1115 ADC
00:40module at just $3.74. It's sold almost 5,000 times and holds a 4.9-star rating, which tells
00:48you a lot.
00:49The ADS-1115 chip itself is the star here, a genuine Texas instrument spark with 16-bit resolution and a
00:56programmable gain amplifier that goes all the way up to a gain of 16. That's the feature I care about
01:01most because it means you can measure small voltage changes like 100 millivolts across a sensor and
01:07still get usable resolution. For anyone starting out, this is the best value on the list, period.
01:14Now, if you hate jumper wires, this next one is going to save your evening.
01:19This 1-PCS or 3-PCS bundle with stem-acuity and quiet-compatible connectors runs $4.02. It's sold
01:26over 4,500 times, and it's got a perfect 5-star rating. The connectors are the whole point,
01:32these boards plug straight into Adafruit gear, Raspberry Pi Pico, or ESP32 boards with a single
01:37cable, no solder, no breadboard mess. And you can grab the 3-pack version if you're running multiple
01:43channels. For plug-and-play projects, this is the one I'd buy. Third option is the 16-bit ADS-1115
01:51module with the ProGain amplifier for $4.44, around $4.583 sold, rated 4.8. Slightly pricier, and the
02:00reason is hardware. These boards tend to come with a larger footprint, clearly labeled pins,
02:05onboard voltage regulation, and level shifting so you can run it off either 3.3 or 5 volts without
02:11frying anything. Some variants even break out screw terminals for your sensor wires.
02:17The best feature is honestly how forgiving it is to wire up. If you're new to this stuff and want
02:23zero debugging headaches, that extra dollar buys you a lot of saved time. Now, the budget pick.
02:29The ZY-ADS-1115 for 16-bit ADC module with I2C communication is only $2.87, and it's still sold
02:38more than 4,000 times with a 5-star rating. You get the same core promise, 4 channels, 16 bits,
02:44I2C, for the cheapest price of any full module here. And here's the trick, when you're building
02:49something with 3 or 4 sensors, buying these individually still costs you less per board
02:54than the premium modules. For student builds, batch orders, or anything where quantity matters
02:59more than polish, this one's hard to argue with. Note, no LTC 2353 or LTC 2357 parts appear in the
03:07product list, all 5 items are ADS-1115 based. Script written around the actual inventory,
03:14swap in the title to match your listing if those chips are elsewhere.
