LM321
Single Rail-to-Rail Output
Operational Amplifier
GENERAL DESCRIPTION
FEATURES
The LM321 is a single high-gain frequency-compensated
operational amplifier, which can operate from 3V to 32V
single supply or from ±1.5V to ±16V dual supplies while
consuming only 240μA quiescent current.
• Wide Supply Ranges
Single Supply: 3V to 32V
Dual Supplies: ±1.5V to ±16V
• Low Quiescent Current: 240μA (TYP)
• Low Input Offset Voltage: 5.8mV (MAX)
• Low Input Offset Current: 20pA (TYP)
• Low Input Bias Current: 10pA (TYP)
• Minimum Input Common Mode Voltage: (-VS) - 0.1V
• Maximum Differential Input Voltage: +32V/-32V
• Gain-Bandwidth Product: 1.1MHz
• Open-Loop Differential Voltage Gain: 111dB (TYP)
• Internal Frequency Compensation
• 0℃ to +70℃ Operating Temperature Range
• Available in a Green SOT-23-5 Package
The LM321 features low power, low offset voltage and
low bias current. It is well suited for a wide range of
applications.
The LM321 is available in a Green SOT-23-5 package. It
is specified over the 0℃ to +70℃ temperature range.

ESD Susceptibility
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

OVERSTRESS CAUTION
(TOP VIEW)
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
