SGM8278-2

High-Performance, High-Reliability Analog ICs – SGMICRO

Low Noise, High Voltage, Rail-to-Rail I/O Operational Amplifier

The SGM8278-2 is a dual, low noise, precision, high voltage operational amplifier, which can operate from 3V to 36V single supply or from ±1.5V to ±18V dual power supplies. It provides rail-to-rail input with a wide input common mode voltage range and rail-to-rail output voltage swing.

The SGM8278-2 provides high slew rate, low noise, low offset, drift and bias current.

The SGM8278-2 is available in Green SOIC-8, MSOP-8, TDFN-2×2-8AL, TDFN-3×3-8BL and WLCSP-1.57×1.57-8B packages. It is specified over the extended -40℃ to +125℃ temperature range.
