     DESCRIPTION
   The UTC LM324 consists of four independent, high gain
internally frequency compensated operational amplifiers which are                                      DIP-14
designed specifically to operated from a single power supply over a
wide voltage range. Operation from split power supplies is also
possible. Application areas include transducer amplifier, DC gain
blocks and all the conventional OP amp circuits which now can be
easily implemented in single power supply system.                                                     TSSOP-14

     FEATURES
*Internally frequency compensated for unity gain.                          *Pb-free plating product number: LM324L
*Large DC voltage gain :100dB.
*Wide operating supply range (Vcc=3V~32V).
*Input common-mode voltage includes ground.
*Large output voltage swing: From 0V to Vcc-1.5V.
*Power drain suitable for battery operation.
