50MHz, Rail-to-Rail Output CMOS Operational Amplifier
50MHz, Rail-to-Rail Output CMOS Operational Amplifier

The SGM8651/2/3/4/5 are high precision, low noise, low distortion, rail-to-rail output CMOS voltage feedback operational amplifiers offering ease of use and low cost. They have a wide input common mode voltage range and output voltage swing, running at single-supply voltage from 2.5V to 5.5V.

Despite being low cost, the SGM8651/2/3/4/5 provide excellent overall performance. They offer wide gain-bandwidth product to 50MHz and a typical low power of 2.3mA/amplifier.

The SGM8651/2/3/4/5‘s low distortion and fast settling make them ideal for buffering high speed A/D or D/A converters. The SGM8653/5 has a power-down disable feature that reduces the supply current to 75μA/amplifier. These features make the SGM8653/5 ideal for portable and battery-powered applications where size and power are critical. All are specified over the extended -40 to +125 temperature range.
