The LT1078/LT1079 are Texas Instruments' micropower dual- and quad-channel single-supply precision op amps, with a maximum supply current of 50µA and a low voltage noise of 0.6µVP-P, 0.1Hz to 10Hz.
The LT1078 is a micropower dual op‑amp and the LT1079 a micropower quad op‑amp, both optimized for single‑supply operation at 5 V (with +15 V options). They offer ultra‑low offset voltage, low offset current, low noise, and can source or sink up to 5 mA without pull‑down resistors, making them suitable for battery‑powered and portable instrumentation.
The document lists detailed electrical characteristics such as input offset voltage, gain‑bandwidth product, slew rate, and supply current, as well as typical performance graphs and extensive package descriptions for SO, DIP, and plastic‑outline options. Absolute maximum ratings and ordering information are also provided.
