Zero-crossover op amp for portables claims lowest power

摘要

Offered as the industry's lowest-power zero-cross-over operational amplifier, the OPA369 achieves rail-to-rail performance without input crossover to solve the common design problem of input offset distortion due to the change in common-mode voltage that is very prominent in low-voltage rail-to-rail applications. Featuring 1-μA quiescent current, an SC70 package, and operation down to 1.8 V, the op amp simplifies high-performance designs in battery-powered portable products.
