sg micro micro power opamps sgm8049-1 - 1.8v, 2.5μa, 120khz, rail-to-rail i/o operational amplifiers
[datasheet]
general description
the sgm8049-1, sgm8049-2 and sgm8049-4 micro power, low voltage operational amplifiers are designed for battery-powered applications. the amplifiers operate on a supply voltage as low as 1.8v (±0.9v). high-performance, single-supply operation with rail-to-rail capability makes the sgm8049-1/-2/-4 useful for a wide range of applications.
in addition of small packages, the sgm8049-1/-2/-4 feature impressive bandwidth, low bias current and low noise relative to the very low quiescent current.
the single sgm8049-1 is available in green sc70-5, sot-23-5 and tdfn-2×2-6l packages. the dual sgm8049-2 is available in green sot-23-8 and soic-8 packages. the quad sgm8049-4 is available in green tssop-14 package. they are specified over the extended -40℃ to +125℃ temperature range.
