    SGM8557-1

    GENERAL DESCRIPTION

    The SGM8557-1 (single), SGM8557-3 (single with shutdown), SGM8557-2 (dual) and SGM8557-5 (dual with shutdown) high output drive CMOS operational amplifiers feature a peak output current of 240mA, rail-to-rail output capability from a single 2.7V to 5.5V supply. These amplifiers exhibit a high slew rate of 7V/μs and a gain-bandwidth product (GBP) of 15MHz. The SGM8557-3/5 offer a shutdown feature that drives the output low.

    The SGM8557-1/2/3/5 offer low input offset voltage, low input offset voltage drift, wide bandwidth and high output drive.

    The SGM8557-1 is available in Green SOIC-8, MSOP-8 and SOT-23-5 packages. The SGM8557-2 is available in a Green SOIC-8 package. The SGM8557-3 is available in Green SOIC-8 and SOT-23-6 packages. The SGM8557-5 is available in a Green MSOP-10 package. They operate over an ambient temperature range of -40 to +125.
