LT6003/LT6004/LT6005 is a low power op amp from Texas Instruments. It can operate in a wide voltage range of 1.6V to 16V and has low static current and high precision. It is very suitable for portable applications.
The LT6003/LT6004/LT6005 family are single, dual, and quad operational amplifiers designed for ultra‑low power consumption in portable and battery‑powered applications. They operate from a wide supply range of 1.6 V to 16 V, feature a low input offset voltage of 500 µV max, low input bias current of 90 pA max, and high CMRR (100 dB) and PSRR (95 dB).
These devices are offered in several compact packages, including 5‑pin TSOT‑23, 2 mm × 2 mm DFN, 8‑lead MSOP, and 16‑lead TSSOP, with temperature grades covering –40 °C to 125 °C. The document includes detailed electrical characteristics, ordering codes, typical application circuits such as micropower gas sensors, and related part references.
