CMOS Operational Amplifier
FEATURES
PRODUCT DESCRIPTION
• Low Cost
The SGM8541 (single) ，SGM8542 (dual) and SGM8544
(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 +125°C temperature range.
• Rail-to-Rail Input and Output
0.8mV Typical VOS
• Unity Gain Stable
• Gain Bandwidth Product: : 1.1MHz
• Very low input bias currents : 0.5pA
• 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: 42µA/Amplifier
• Small Packaging
The SGM8541/8542/8544 provide 1.1MHz bandwidth at
a low current consumption of 42µA per amplifier. Very
low input bias currents of 0.5pA, enable SGM8541/8542
/8544 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.
SGM8541 Available in SO-8 and SOT23-5
SGM8542 Available in SO-8 and MSOP-8
SGM8544 Available in SO-16 and TSSOP-16
Applications for this amplifiers include safety monitor-
ing, portable equipment, battery and power supply
control, and signal conditioning and interfacing for
transducers in very low power systems.
