SGM8621/2/3/4
250μA, 3MHz, Rail-to-Rail I/O
CMOS Operational Amplifiers
PRODUCT DESCRIPTION
FEATURES
The SGM8621 (single), SGM8622 (dual), SGM8623
(single with shutdown) and SGM8624 (quad) are low
noise, low voltage, and low power operational amplifiers,
that can be designed into a wide range of applications.
The SGM8621/2/3/4 have a high gain-bandwidth product
of 3MHz, a slew rate of 1.7V/μs, and a quiescent current
Low Cost
Rail-to-Rail Input and Output
0.7mV Typical VOS
High Gain-Bandwidth Product: 3MHz
High Slew Rate: 1.7V/μs
Settling Time to 0.1% with 2V Step: 2.1μs
Overload Recovery Time: 1μs
of 250μA/amplifier at 5V. The SGM8623 has
a
power-down disable feature that reduces the supply
current to 150nA.
Low Noise: 12nV/
Hz
Supply Voltage Range: 2.5V to 5.5V
Input Voltage Range: -0.1V to +5.6V with VS = 5.5V
Low Supply Current
The SGM8621/2/3/4 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 is 3mV for
SGM8621/2/3/4. They are specified over the extended
industrial temperature range (-40℃ to +125℃). The
operating range is from 2.5V to 5.5V.
