PRODUCT DESCRIPTION

The SGM8631(single), SGM8632(dual), SGM8633(single

with shutdown) and SGM8634 (quad) are low noise, low

voltage, and low power operational amplifiers, that can be

designed into a wide range of applications. The

SGM8631/2/3/4 have a high gain-bandwidth product of

6MHz, a slew rate of 3.7V/μs, and a quiescent current of

470μA/amplifier at 5V. The SGM8633 has a power-down

disable feature that reduces the supply current to 90nA.

The SGM8631/2/3/4 are designed to provide optimal

performance in low voltage and low noise systems. They

provide rail-to-rail output swing into heavy loads. The

input common-mode voltage range includes ground, and

the maximum input offset voltage are 3.5mV for

SGM8631/2/3/4. They are specified over the extended

industrial temperature range (−40°C to +125°C). The

operating range is from 2.5V to 5.5V.

The single version, SGM8631/8633, is available in SC70-5,

SO-8 and SOT23-5(6) packages. The dual version SGM8632

is available in SO-8 and MSOP-8 packages. The quad

version SGM8634 is available in SO-16 and TSSOP-16

packages.
