OPA369/2369


The Industry's Lowest Power Zero-Crossover Operational Amplifier

Featuring a unique single-input-stage architecture, the OPA369 achieves rail-to-rail performance without input crossover. This architecture solves 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. With features of 1µA quiescent current, SC70 package and operation down to 1.8V, the OPA369 simplifies high-performance designs in battery-powered, portable products. Generally, single supply designers must choose between power budget and AC or DC performance of their signal conditioning amplifiers. The OPA369/2369 combines TI's Zero-Crossover input topology and next generation CMOS process technology to offer precision performance not previously seen in a 1µA single supply amplifier.

TI provides customers with a state-of-the-art signal chain solution for portable applications: analog-to-digital converters such as the ADS8326; digital-to-analog converters such as the DAC8560; and precision voltage references such as the REF33xx. The OPA369 is also optimized to work with TI's MSP430 ultra-low-power microcontroller family.
