GENERAL DEscriptION

The SGM8091/3 (single), SGM8092 (dual) and SGM8094 (quad) are high speed operational amplifiers, which can operate from 2.5V to 5.5V single supply. The SGM8091/2/3/4 feature an 8mV maximum input offset voltage and offer a low supply current of 4.3mA/amplifier.

The SGM8091/2/3/4 have excellent performance. They have a bandwidth and slew rate usually exist in current feedback amplifiers. They exhibit a wide bandwidth of 350MHz (G = +1) and a 0.1dB gain flatness of 70MHz (G = +1).

The SGM8091/2/3/4 provide wide input common mode voltage range and rail-to-rail output swing. The fast settling time and low distortion make the operational amplifiers appropriate for high speed ADC/DAC. The supply current of SGM8093 is 75μA in shutdown mode. The devices are suitable for use in portable instrumentation and battery-powered systems. They are specified over the extended -40℃ to +125℃ temperature range.
