The LT6013/LT6014 is a single/dual 145µA, 9.5nV/√Hz, AV≥5, rail-to-rail output precision op amp. It features low noise, high precision input performance, low power consumption and rail-to-rail output swing. The amplifier is stable in a gain of 5 or more and features greatly improved CMRR and PSRR versus frequency compared to other precision op amps. Input offset voltage is factory-trimmed to less than 35µV. The low drift and excellent long-term stability ensure a high accuracy over temperature and time. The 250pA maximum input bias current and 145µA supply current make this amplifier very suitable for battery-powered precision systems and low-voltage precision systems. It can be used for thermocouple amplifiers, precision photodiode amplifiers, instrumentation amplifiers, micro-power sensor interfaces and other applications.
The LT6013 and LT6014 precision op‑amps combine ultra‑low offset voltage (35 µV max) and low input bias current (250 pA) with rail‑to‑rail output swing and a supply‑current of only 145 µA per amplifier. They operate from 2.7 V to 36 V and are stable at gains of 5 or higher, offering a 1.4 MHz gain‑bandwidth product and a 0.2 V/µs slew rate.
These devices are suited for thermocouple amplifiers, precision photodiode amplifiers, instrumentation, battery‑powered precision systems, low‑voltage precision circuits, and micro‑power sensor interfaces. They are offered in SO‑8 and space‑saving 3 mm × 3 mm DFN packages, with detailed pin‑out and solder‑pad dimensions provided for PCB designers.
