Adafruit ADS7830 8-Channel 8-Bit ADC with I2C - STEMMA QT / Qwiic

Many microcontrollers have ADCs, but sometimes you need more channels or are using a single board computer like a Raspberry Pi without ADCs. The Adafruit ADS7830 8-Channel 8-Bit ADC with I2C is an affordable 8-channel ADC breakout with an I2C interface, making it easy to interface with any platform.

Only four wires are needed: SDA, SCL, power, and ground. The ADS7830 supports up to 70 Ksamples per second at 8-bit resolution, suitable for rough sensor measurements such as potentiometers or flex sensors, but not precision thermistor conversions.

This product uses the STEMMA QT form factor with compatible connectors to SparkFun Qwiic connectors, enabling solderless connections and chaining multiple sensors or accessories easily using compatible cables (cable not included).

• 8 analog input channels
• 8-bit resolution
• I2C interface with two address pins for up to 32 channels
• Sample rate up to 70 ksps (requires 3.4 MHz I2C bus speed)
• Operates from 3V to 5V power and logic levels
• External or internal reference voltage support
• Compact PCB with STEMMA QT connectors and breadboard-compatible 0.1" headers
• Four mounting holes for easy attachment
