50MHz, Low Distortion, RRIO, Single Supply Operational Amplifier

The SGM8965-1/2 zero-crossover series, rail-to-rail input and output, high-performance, CMOS operational amplifiers are optimized for low voltage, single-supply applications. Rail-to-rail input and output, low noise and high speed operation make these devices ideal for driving sampling analog-to-digital converters (ADCs). Applications include audio, signal conditioning and sensor amplification. The SGM8965-1/2 family of operational amplifiers is also well-suited for cell phone power amplifier control loops.

Special features include no input stage crossover distortion, high input impedance, and rail-to-rail input and output swing. The input common mode voltage range includes both the negative and positive supplies. The output voltage swing is within 8mV of the rails.

The SGM8965-1 (single version) is available in Green SOT-23-5 and SOIC-8 packages. The SGM8965-2 (dual version) is available in Green SOIC-8 and MSOP-8 packages. All versions are specified for operation from -40 to +125. Single and dual versions have identical specifications for maximum design flexibility.
