Maintaining high precision in industrial applications
BOM costs are lowered due to reduced signal chain complexity and the number of external components.

Texas Instruments announced the release of an operational amplifier product that offers both zero drift and zero crossover technologies.

The OPA388 operational amplifier maintains high precision across the entire input range in various industrial applications such as test, instrumentation, medical and safety equipment, and high-resolution data acquisition systems.

TI stated that the OPA388's zero drift technology eliminates temperature drift and flicker noise, enabling maximum DC precision and dynamic error correction, and the zero crossover topology eliminates offset errors caused by common mode constraints, providing linear output and true rail-to-rail input operation.



To help designers using the OPA388 understand the process, TI provides various support tools, including reference designs that demonstrate how to use precision operational amplifiers to eliminate crossover nonlinearity in digital-to-analog converters.

This reference design incorporates the DAC8830 precision data converter and the REF5050 voltage reference; these devices are combined to form an accurate DC calibration system, which can be used for high-precision applications in wireless infrastructure, test, and measurement equipment.
