Texas Instruments (TI) has introduced what it calls the smallest 24 bit wideband analog-to-digital converter (ADC) that delivers signal-measurement precision at wider bandwidths than competing ADCs.

The ADS127L11, which is the latest product in TI's portfolio of precision wideband ADCs, achieves ultra-precise data acquisition in a 50% smaller package, significantly optimizing power consumption, resolution and measurement bandwidth for a wide range of industrial systems.

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.

Until recently, 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 x 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.

The ADS127L11 reportedly 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.

The ADS127L11 is available for purchase on TI.com, and comes in a 20 pin, 3 mm x 3 mm WQFN package or a 20 pin, 6.5 mm x 4.4 mm thin shrink small-outline package (TSSOP). Pricing starts at $5.75 in 1,000-unit quantities.
