Automotive 2.2V, 50MHz, Low-Noise Single-Supply Rail-to-Rail Operational Amplifiers - OPA2365-Q1

OPA2365-Q1 (ACTIVE)

Automotive 2.2V, 50MHz, Low-Noise Single-Supply Rail-to-Rail Operational Amplifiers

 

Description

The OPAx365-Q1 zero-crossover family, rail-to-rail, high-performance, CMOS operational amplifiers are optimized for very low voltage, single-supply applications. Rail-to-rail input/output, low noise (4.5 nV/√Hz) and high speed operation (50-MHz gain bandwidth) make these devices ideal for driving sampling data converters (such as the ADS7822-Q1 or the ADS1115-Q1), specifically in short to mid-range radar applications. The OPAx356-Q1 family of operational amplifiers are also well-suited for HEV/EV and Powertrain applications in DC-DC converters and as transmission control in engine control units.

Special features include an excellent common-mode rejection ratio (CMRR), no input stage crossover distortion, high input impedance, and rail-to-rail input and output swing. The input common-mode range includes both the negative and positive supplies. The output voltage swing is within 10 mV of the rails.

The OPA365-Q1 (single version) is available in the 5-pin SOT-23 package. The OPA2365-Q1 (dual version) is available in the 8-pin SOIC package. All versions are specified for operation from −40°C to 125°C. Single and dual versions have identical specifications for maximum design flexibility.
