Zero-drift, zero-crossover operational amplifier achieves true precision

Texas Instruments has introduced what is claimed to be the first operational amplifier (op amp) to offer both zero-drift and zero-crossover technology. The OPA388 op amp maintains high precision across the entire input range for a variety of industrial applications, including test and measurement, medical and safety equipment, and high-resolution data-acquisition systems. The unique architecture of the device produces an industry-leading combination of ultra-high input linearity and precision. The company’s zero-drift technology eliminates temperature drift and flicker noise to attain the highest DC precision and dynamic error correction, while its zero-crossover topology eliminates offset errors caused by common-mode limitations to achieve linear output and true rail-to-rail input operation.
