SGM321/SGM358/SGM324
1MHz, 60μA, Rail-to-Rail I/O
CMOS Operational Amplifiers
GENERAL DESCRIPTION
The SGM321 (single), SGM358 (dual) and SGM324
(quad) are low cost, rail-to-rail input and output voltage
feedback amplifiers. They have a wide input common
mode voltage range and output voltage swing, and take
the minimum operating supply voltage down to 2.1V.
The maximum recommended supply voltage is 5.5V.
All are specified over the extended -40℃ to +85℃
temperature range.
The SGM321/358/324 provide 1MHz bandwidth at a
low current consumption of 60μA per amplifier. Very
low input bias currents of 10pA enable SGM321/358/324
to be used for integrators, photodiode amplifiers, and
piezoelectric sensors. Rail-to-rail input and output are
useful to designers for buffering ASIC in single-supply
systems.
Applications for this series of amplifiers include safety
monitoring, portable equipment, battery and power
supply control, and signal conditioning and interfacing
for transducers in very low power systems.
The SGM321 is available in the Green SOT-23-5 and
SC70-5 packages. The SGM358 comes in the Green
SOIC-8, MSOP-8 and DIP-8 packages. The SGM324 is
offered in the Green SOIC-14 and TSSOP-14
packages.
