1.8V, 700nA, Zero-Crossover Rail-To-Rail I/O Operational Amplifier

1.8V, 700nA, Zero-Crossover Rail-To-Rail I/O Operational Amplifier - OPA369
 

Description

The OPA369 and OPA2369 are ultra-low-power, low-voltage operational amplifiers from TexasInstruments designed especially 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 zerø-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, the OPAx369 features 12kHz bandwidth, low offset drift (1.75µV/°C, max), and low noise 3.6µVPP (0.1Hz to 10Hz).

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