OPA301 - Low-Noise, High-Speed,16-Bit Accurate CMOS Operational Amplifier

Updated : 2020-01-09 14:17:52
Description

The OPA300 and OPA301 series high-speed, voltage-feedback, CMOS operational amplifiers are designed for 16-bit resolution systems. The OPA300/OPA301 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 OPA300/OPA301 series offer superior output swing and excellent common-mode range.

The OPA300 and OPA301 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 OPA300 and OPA301 are available in SO-8 and SOT-23 packages. The OPA2300 is available in MSOP-10, and the OPA2301 is available in SO-8 and MSOP-8. All versions are specified over the industrial temperature range of –40°C to +125°C.
