Quadruple Operational Comparator
LM324QD
Spec. No. : C564QD
Issued Date : 2012.12.11
Revised Date :
Page No. : 1/10
Description
The LM324QD consists of four independent high gain, internally frequency compensated operational
amplifiers which are designed specifically to operate from a single power supply over a wide range of
voltages. Operation from split power supplies is also possible and the low power supply current drain is
independent of the magnitude of the power supply voltage.
Features
• Wide range of supply voltages
•Low supply current drain independent of supply voltage
• Low input biasing current
•Low input offset voltage and offset current
• Differential input voltage range equal to the power supply voltage
• Input common-mode voltage range includes ground
• DC voltage gain 100V/mV typ
•Internally frequency compensation
Applications
• General purpose amplifier
• Transducer amplifier
• DC gain block
