LM321
Single Channel Operational
Amplifier
LM321 is a general purpose, single channel op amp with internal
compensation and a true differential input stage. This op amp features
a wide supply voltage ranging from 3 V to 32 V for single supplies and
±1.5 to ±16 V for split supplies, suiting a variety of applications.
LM321 is unity gain stable even with large capacitive loads up to
1.5 nF. LM321 is available in a space-saving TSOP−5/SOT23−5
package.
