Breakout Boards / ADC / DAC

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller...

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller...

Your microcontroller probably has an ADC (analog -> digital converter) but does it have a DAC (digital -> analog converter)??? Now it can! This breakout board features the easy-to-use MCP4725 12-bit DAC. Control it via I2C and send it the value you want it to output, and the VOUT pin will have it. Great for audio / analog projects, such as when you can't use...

If you are feeling the stress and strain of modern life a Wheatstone bridge and you want to quantify it, this handy breakout will do the job, no sweat! The Adafruit HX711 Breakout contains a super-high-resolution 24-Bit differential ADC with extra gain circuitry that makes it perfect for measuring strain gauges / load cells or other sensors that have four wires that...

We stock a lot of chips and development boards that are able to do high quality digital I2S out, which makes for great quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real time. However, most give you stereo line-out which cannot connect to head-phones...until now! We really love the sounds coming out of the...

If you've ever said to yourself, "Gee, I wish I had four 12-bit DACs that came in a single package with the ability to save their settings to an EEPROM", well I have good news. The MCP4728 is the answer to your wishes! Within its little package, the MCP4728 has four 12-bit DACs for whatever voltage setting needs you may have. In addition, it has the ability to store...

Low cost Lithium Polymer batteries have revolutionized electronics - they're thin, they're light, they can be regulated down to 3.3V and they're easy to charge. On your phone, there's a little image of a battery cell that tells you the percentage of charge - so you know when you absolutely need to plug it in and when you can stay untethered. The Adafruit LC709203F...

Many microcontrollers have ADCs these days, for reading analog/resistive sensors like potentiometers, thermistors, LDR light sensors, etc. but sometimes you need MOAR! Or maybe you're using a single board computer like a Raspberry Pi that has no ADCs at all! The Adafruit ADS7830 8-Channel 8-Bit ADC with I2C is an affordable 8-channel ADC with I2C interface, so it's...

Which is better, less bits or more? MORE of course! So why settle for a 12-bit DAC like the MCP4725 when you can go for the 16-bits of the AD5693? OK well there may be some reason to go with 12-bits, say if you don't need high resolution output and want to go with the more affordable DAC. But for those who like the finer things in life, the Adafruit AD5693R Breakout...

We stock a lot of chips and development boards that are able to do high quality digital I2S out, which makes for great quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real time. However, we don't have a good selection of I2S DAC boards...until now! We really love the sounds coming out of the Adafruit PCM5100 I2S...

Measuring voltage and adjusting it is what electronics is all about so you won’t get far without friends like the Adafruit PCF8591 Quad 8-bit ADC + 8-bit DAC combo. Analog to Digital Converters help by measuring an analog voltage and turning it into something a microcontroller like a Metro or Arduino can understand. If you’re using a single-board computer...

If you've ever said to yourself, "Gee, I wish I had eight 10-bit DACs that came in a single package", well I have good news. The Adafruit DAC6578 Breakout is the answer to your wishes! Within its little package, the DAC6578 has eight 10-bit DACs for whatever voltage setting needs you may have, easily controlled over I2C. The DAC6578 can easily work with 3.3V or 5V...

The Adafruit MCP3421 18-Bit ADC is a simple, inexpensive, and easy to use 18-bit, 240 SPS, single-channel ADC with an I2C interface that can run up to 3.4MHz clock rate. A perfect component whenever you need an ADC that has differential inputs, adjustable gain, and a built in precision/low-drift reference voltage. One of the trade-offs with getting 18-bit precision...
