SGM8049-1/SGM8049-2/SGM8049-4
1.8V, 2.5µA, 120kHz,
Rail-to-Rail I/O Operational Amplifiers
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.
