Texas Instruments (TI) has introduced the smallest 24-bit wideband analog-to-digital converter (ADC), which delivers signal-measurement precision at wider bandwidths than competing ADCs.
The ADS127L11, the newest product in TI’s portfolio of precision wideband ADCs, achieves ultra-precise data acquisition in a 50-percent smaller package — significantly optimizing power consumption, resolution, and measurement bandwidth for a range of industrial systems.
“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.”
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-percent wider bandwidth, data rates as high as 400 kSPS, and a 30-percent higher signal-to-noise ratio than competing data converters while minimizing noise at high frequencies.
In low-latency mode, the ADS12711 delivers 25 percent 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.
Until now, miniaturized, 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-percent 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. To learn more about how to optimize channel density by using multiple ADC channels operating in simultaneous-sampling mode, click here.
Extended battery run time
The ADS127L11 consumes half the power of other ADCs, enabling designs such as portable electroencephalogram (EEG) machines and power-quality analyzers to better optimize 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.
