Product Overview
The 7Semi ADS1263 32-bit ADC with PGA Breakout is a high-precision analog-to-digital converter designed for applications requiring exceptional accuracy, such as weigh scales, strain-gauge sensors, thermocouples, and RTDs. It features the Texas Instruments ADS1262 ADC, offering low-noise and low-drift performance. The module includes an integrated programmable gain amplifier (PGA) and voltage reference, ensuring precise measurements. It supports data rates from 2.5 SPS to 38,400 SPS and provides an auxiliary 24-bit delta-sigma ADC for concurrent background measurements. Additional features include a single-cycle settling digital filter, robust fault monitoring, and dual sensor excitation current sources, making it ideal for direct RTD measurements.
