ADS1263IPWR

适用于工厂自动化且具有 PGA、基准电压和辅助 ADC 的 32 位 38kSPS 10 通道 Δ-Σ ADC 28-TSSOP -40 to 125

The ADS1262 and ADS1263 are low-noise, low-drift, 38.4-kSPS, delta-sigma ΔΣ ADCs with an integrated PGA, reference, and internal fault monitors. The ADS1263 integrates an auxiliary, 24-bit, ΔΣ ADC intended for background measurements. The sensor-ready ADCs provide complete, high-accuracy, one-chip measurement solutions for the most-demanding sensor applications, including weigh scales, strain-gauge sensors, thermocouples, and resistance temperature devices RTD.

The ADCs 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.

A single-cycle settling digital filter maximizes multiple-input conversion throughput, while providing 130-dB rejection of 50-Hz and 60-Hz line cycle interference.

The ADS1262 and ADS1263 are pin and functional compatible. These devices are available in a 28-pin TSSOP package and are fully specified over the –40°C to +125°C temperature range.
