The OPA300, OPA301, OPA2300, and OPA2301 (OPAx30x) series high-speed, voltage-feedback, CMOS operational amplifiers are designed for 16-bit resolution systems. The OPAx30x series are unity-gain stable and feature excellent settling and harmonic distortion specifications. Low power applications benefit from low quiescent current. The OPA300 and OPA2300 feature a digital shutdown (enable) function to provide additional power savings during idle periods. Optimized for single-supply operation, the OPA30x series offer high output swing and excellent common-mode range.

The OPAx30x series op amps have 150MHz of unity-gain bandwidth, low 3nV/√Hz voltage noise, and 0.1% settling within 30ns. Single-supply operation from 2.7V (±1.35V) to 5.5V (±2.75V) and an available shutdown function that reduces supply current to 5µA are useful for portable low-power applications. The OPAx30x are available in SO-8 and SOT-23 packages. The OPA2300 is available in VSSOP-10, and the OPA2301 is available in SO-8 and VSSOP-8. All versions are specified over the industrial temperature range of −40°C to +125°C.
