Texas Instruments - Highly-integrated low-noise low-drift 38.4-kSPS delta-sigma ADCs (ADS1262)

Texas Instruments' new ADS1262 and ADS1263 are low noise, low drift, 38.4kSPS, delta-sigma (ΔΣ) ADCs with integrated PGA, voltage reference and internal fault monitor. The ADS1263 integrates an auxiliary 24-bit ΔΣ ADC for background measurement. Sensor-oriented ADCs provide complete, high-precision single-chip measurement solutions for the most demanding sensor applications, including scales, strain gauge sensors, thermocouples, and resistance temperature devices (RTDs). These ADCs include a low noise CMOS PGA (gains from 1 to 32), a delta-sigma modulator, and a programmable digital filter. The flexible analog front end (AFE) contains two sensor excitation current sources for direct RTD measurements. A single-cycle digital filter can maximize the throughput of multiple input conversions, while providing 130dB rejection of 50dB and 60Hz line cycle interference. The ADS1262 and ADS1263 are pin and function compatible. These devices are available in 28-lead TSSOP packages and have full specifications over the -40C to + 125C temperature range.
