LT1013/LT1014

Quad Precision Op Amp (LT1014) Dual Precision Op Amp (LT1013) FEATURES DESCRIPTIO ®1014 is the first precision quad operational amplifier

Single Supply Operation The LT Input Voltage Range Extends to Ground which directly upgrades designs in the industry standard Output Swings to Ground while Sinking Current 14-pin DIP LM324/LM348/OP-11/4156 pin configuration. Pin Compatible to 1458 and 324 with Precision Specs It is no longer necessary to compromise specifications, Guaranteed Offset Voltage: 150μV Max while saving board space and cost, as compared to single
