LT2078/LT2079 are low-power dual and quad single supply precision op amps. Its features are low power consumption, large output current, large output swing.
The LT2078 (dual) and LT2079 (quad) are micropower operational amplifiers offered in 8‑lead and 14‑lead SO packages. Both devices are optimized for single‑supply operation at 5 V and provide input voltage ranges that include ground, allowing operation from a single lithium cell or two NiCd batteries.
Key features include ultra‑low offset voltage (as low as 30 µV), low offset current (250 pA), low voltage noise (0.6 µV p‑p from 0.1 Hz to 10 Hz), a gain‑bandwidth product of 200 kHz, and a slew rate of 0.07 V/µs. The output stage can swing to ground while sinking current without pull‑down resistors, making the devices suitable for battery‑powered instrumentation, sensor interfaces, and thermocouple amplification.
