CMOS Operational Amplifier
FEATURES
PRODUCT DESCRIPTION
• Low Cost
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.
• Rail-to-Rail Input and Output
0.8mV Typical VOS
• Unity Gain Stable
• Gain Bandwidth Product: 1MHz
• Very Low Input Bias Currents: 10pA
• Operates on 2.1 V to 5.5 V Supplies
• Input Voltage Range:
- 0.1 V to +5.6 V with VS = 5.5 V
• Low Supply Current: 60µA/Amplifier
• Small Packaging
SGM321 Available in SOT23-5 and SC70-5
SGM358 Available in SO-8, MSOP-8 and PDIP-8
SGM324 Available in SO-14, SO-16, TSSOP-14 and
TSSOP-16
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.
PIN CONFIGURATIONS (Top View)
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.
