LM2902D

TIGER ELECTRONIC CO.,LTD LM2902N/D Q UAD O PERAT IONAL A MPLIFIER DESCRIPTION T he L M 2902 c onsist of four independent, h igh gain, internally f requency c om p ensated o perational am plifiers which were designed s pecifically to operate from a s ingle power s upply o ver a wide voltage range. Operation f rom s plit power supplies is also possible and t he low power supply c urrent drain is i ndependent of the m a gnitude of the power s upply v oltage. Application areas include t ransducer a m plifier, DC gain b locks and all the DIP14 O utline Drawing L M 2902 LM2902N c onventional OP am p circuits which now can b e easily i m plem ented in single power s upply s y stem s.
