SGM8055
250MHz, Rail-to-Rail Output CMOS Operational Amplifier
250MHz, Rail-to-Rail Output CMOS Operational Amplifier
GENERAL DESCRIPTION

The SGM8051/3 (single), SGM8052/5 (dual) and SGM8054 (quad) are low cost, high speed, rail-to-rail output, voltage feedback amplifiers. They have a wide input common mode voltage range and output voltage swing, making them easy to be used on single supply as low as 2.5V.

Despite being low cost, the SGM8051 series provide excellent overall performance. They offer wide bandwidth to 250MHz (G = +1) along with 0.1dB flatness out to 37MHz (G = +2) and offer a typical low current consumption of 2.3mA/amplifier.

Low distortion and fast settling make the SGM8051 series ideal for buffering high speed A/D or D/A converters. The SGM8053/5 have a power-down disable feature that reduces the supply current to 75μA. This feature makes the SGM8053/5 ideal for portable and battery-powered applications where power dissipation is critical. All are specified over the extended -40 to +125 temperature range.
