SGM324
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
take the minimum operating supply
voltage down to 2.1V and the maximum recommended
supply voltage is 5.5 V.
All are specified over the
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
PDIP-8 packages. The SGM324 is offered in SO-14,
TSSOP-14, TSSOP-16 and SO-16 packages.
