Wideband ADC pushes data-acquisition performance higher

Texas Instruments (TI) has introduced a 24-bit wideband analogue-to-digital converter (ADC) that delivers industry-leading signal-measurement precision at wider bandwidths than many competing ADCs.

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

The device 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 minimising 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.

The ADS127L11 comes in a 3-mm-by-3-mm quad flat no-lead (WQFN) package, and is 50% smaller than most 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.

Power consumption is as low as 3.3 mW with sampling rates as high as 50 kSPS, improving signal resolution and battery life.
