ADS1263 32-bit ADC Module with PGA Breakout - 7Semi
ADS1263 32-bit ADC Module with PGA Breakout - 7Semi The 7Semi ADS1263 32-bit ADC Module with PGA Breakout is a high-accuracy data acquisition solution built around the Texas Instruments ADS1262 chip. Designed for demanding applications like weigh scales, RTDs, thermocouples, and strain-gauge sensors, this module delivers ultra-low noise and minimal drift for reliable performance. It features a built-in Programmable Gain Amplifier (PGA), onboard voltage reference, and dual sensor excitation currents for precision in direct RTD measurements. With a wide range of data rates (2.5 to 38,400 SPS), a 24-bit auxiliary ADC for background tasks, and a single-cycle settling digital filter, it’s ready to handle both fast and highly sensitive measurements. Fault monitoring and flexible interface options make this breakout ideal for industrial and lab-grade applications where accuracy matters most.
