DAC / ADC

USB to GPIO, ADC (10-bit), DAC (5-bit), and I2C bridge with STEMMA QT/Qwiic, USB-C, 4 GPIO, and clock output for quick prototyping.

This 10-bit ADC chip provides 8x analog inputs via SPI. Useful for devices like the Raspberry Pi which doesn't have analog inputs.

The Grove - 4 Channel 16-bit ADC (ADS1115) is a 4-channel 16-bit high-resolution, low-power ADC chip with PGA (programmable gain amplifier) function.

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.

Grove - I2C ADC is a 12-bit precision ADC module based on ADC121C021. It helps you increase the accuracy of value collected from analog sensor by providing a constant reference voltage.

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.

This ADS1015 ADC (analog-to-digital converter) breakout has three channels that can read voltages from -24V to +24V at sampling rates up to 3.3KHz with 12-bit resolution.
