TI’s precision ADC maximises channel density

“There is a clear trend toward smaller solution size and lower power consumption in applications such as test and measurement equipment and portable medical devices, where improved battery life is imperative,” said Noman Akhtar, Senior Research Analyst, Omdia. “There is an urgency to provide increased data throughput, higher bandwidth and lower power, all in a smaller footprint.”

Capture high-resolution signals with 50% wider bandwidth and 25% lower latency

The highly flexible ADS127L11 offers wideband and low-latency filter options to optimise 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.

Reduce ADC footprint with a 50% smaller package

Until now, miniaturised, battery-powered industrial equipment designers had to choose between an ADC’s size and measurement precision at higher frequencies. The ADS127L11 eliminates this trade-off. In a 3-mm-by-3-mm quad flat no-lead (WQFN) package, this single-channel device is 50% smaller than the closest competing ADCs. In addition to reducing design size, the new ADC increases system functionality by enabling designers to pack additional channels into a compact design.

Extend battery run time with 50% lower power consumption

The ADS127L11 consumes half the power of other ADCs, enabling designs such as portable electroencephalogram (EEG) machines and power-quality analysers to better optimise power consumption against bandwidth requirements using the device’s power-scalable modes. Power consumption is as low as 3.3 mW with sampling rates as high as 50 kSPS, improving signal resolution and battery life.
