The highly flexible ADS127L11 offers wideband and low-latency filter options to optimize ADC performance and deliver tailored, high-performance data acquisition in a broad range of industrial systems. Designers can use wideband mode to improve AC measurement resolution with 50% wider bandwidth, data rates as high as 400 kSPS, and a 30% higher signal-to-noise ratio than competing data converters, while minimizing noise at high frequencies. In low-latency mode, the ADS12711 delivers 25% lower latency at up to 1,067 kSPS and 83.3% lower offset drift -- 50 nV/°C -- to help designers improve DC measurement resolution, data throughput and response times in data acquisition and condition-monitoring applications.

Key Points: 
  • "There is an urgency to provide increased data throughput, higher bandwidth and lower power, all in a smaller footprint."
  • The highly flexible ADS127L11 offers wideband and low-latency filter options to optimize ADC performance and deliver tailored, high-performance data acquisition in a broad range of industrial systems.
  • Until now, miniaturized, battery-powered industrial equipment designers had to choose between an ADC's size and measurement precision at higher frequencies.
