PRODUCT DESCRIPTION
The SGM321(single), SGM358(dual) and SGM324(quad)
are rail-to-rail input and output voltage feedback
amplifiers offering low cost. They have a wide input
common-mode voltage range and output voltage
swing, and
voltage down to 2.1V and the maximum recommended
supply voltage is 5.5 V.
extended – 40°C to +85°C 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 inputs and
outputs are useful to designers buffering ASIC in
single-supply systems.
Applications for the series amplifiers include safety
monitor- ing, portable equipment, battery and power
supply control, and signal conditioning and interfacing
for transducers in very low power systems.
The SGM321 is available in SOT23-5 and SC70-5
packages. The SGM358 comes in SO-8,MSOP-8 and
DIP-8 packages. The SGM324 is offered in SO-14,
TSSOP-14, TSSOP-16 and SO-16 packages.
