Texas Instruments ADS126x/ADS126x-Q1 Analog-to-Digital Converters

Texas Instruments ADS126x/ADS126x-Q1 Analog-to-Digital Converters (ADCs) are low-noise, low-drift, 38.4-kSPS, delta-sigma (ΔΣ) ADCs. These come with an integrated PGA, reference, and internal fault monitors. The ADS1263 integrates an auxiliary, 24-bit, ΔΣ ADC intended for background measurements. These sensor-ready ADCs provide complete, high-accuracy, one-chip measurement solutions for the most demanding sensor applications. This includes weight scales, strain-gauge sensors, thermocouples, and resistance temperature devices (RTD). These ADCs from Texas Instruments are comprised of a low-noise, CMOS PGA (gains 1 to 32), a ΔΣ modulator, followed by a programmable digital filter. The flexible analog front-end (AFE) incorporates two sensor-excitation current sources suitable for direct RTD measurement. The ADS126x-Q1 devices are AEC-Q100 qualified for automotive applications.
