Supply Voltage: 3V to 36V  
The LM321A/358A/324A series amplifiers are newest high  
supply voltage amplifiers with low offset, low power and stable  
frequency response. They incorporate 3PEAK’s proprietary and  
patented design techniques to achieve very good AC  
performance with 0.9MHz bandwidth, 0.5V/μs slew rate and  
maximum 3mV offset while drawing only 100μA of quiescent  
current per amplifier. The input common-mode voltage range  
extends to V–, and the outputs swing rail-to-rail. The  
LM321A/358A/324A family can be used as plug-in  
replacements for many commercially available op-amps to  
reduce power and improve input/output range and performance.  
Low Supply Current: 100μA per channel  
Input Common-Mode Voltage Range Includes Ground  
Can Work as Comparator  
Rail to Rail Output  
Bandwidth: 0.9 MHz  
Slew Rate: 0.5V/μs  
Excellent EMI Suppress Performance: 71dB at 1GHz  
Offset Voltage: ±3mV Maximum  
Offset Voltage Temperature Drift: 7 μV/°C  
–40°C to 125°C Operation Temperature Range  
The combination of features makes the LM321A/358A/324A  
ideal choices for power module, industrial control, motor control  
and audio application.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to  
any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.  
Note 2: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 300mV beyond the  
power supply, the input current should be limited to less than 10mA.  
Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power  
supply voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the  
package. The specified values are for short traces connected to the leads.
