Description
The Soldered ADC 24-bit ADS1219 4-channel with PGA breakout adds precision analog measurement to any I2C host. Built around the Texas Instruments ADS1219, a 24-bit delta-sigma converter that samples at up to 1000 SPS with each conversion fully settling on its own, it reaches up to 20 bits of effective resolution at slower data rates. This provides quiet, clean readings usually expected from a much larger instrument. Whether you're logging sensor data, building a battery tester, or reading a load cell, this compact 22 × 22 mm board handles the measurement and sends the result directly to your NULA board, Arduino, or any other microcontroller over I2C.
