Texas Instruments Introduces Lowest Power Zero-Crossover Op Amp

The OPA369 from Texas Instruments precision amplifier is the industry’s lowest power zero-crossover op amp. Featuring a unique single-input stage architecture, the device achieves rail-to-rail performance without input crossover. With 1µA quiescent current, small SC70 package and operation down to 1.8V, the OPA369 simplifies high-performance designs in battery-powered, portable applications.

The OPA369 and OPA2369 are new low-power, low-voltage operational amplifiers from Texas Instruments especially designed for battery-powered applications.

The OPAx369 operates on a supply voltage as low as 1.8V and has true rail-to-rail operation that makes it useful for a wide range of applications. The zero-crossover feature resolves the problem of input crossover distortion that becomes very prominent in low voltage (< 3V), rail-to-rail input applications.

In addition to microsize packages and very low quiescent current (1µA, max) the OPAx369 features 12kHz bandwidth, low offset drift, and low 0.1Hz to 10Hz noise.

The OPA369 (single version, available Q4 2007) is offered in an SC70-5 package. The OPA2369 (dual version) comes in both MSOP-8 and SOT23-8 packages.
