Low-voltage single supply op amps LT1881/LT1882 feature high accuracy input performance and RRO output swing.
The LT1881 and LT1882 are precision operational amplifiers offering rail‑to‑rail output swing, ultra‑low input bias current, and high accuracy offset voltage. They operate from a single or split supply ranging from 2.7 V to 36 V and are suited for thermocouple amplifiers, bridge transducers, instrumentation, and battery‑powered systems.
The devices are available in 8‑lead PDIP and 14‑lead plastic SO packages. Detailed electrical characteristics include offset voltage as low as 50 µV (LT1881A), input bias current down to 200 pA, and a gain‑bandwidth product up to 1 MHz. Typical applications and performance graphs are provided.
