LINEAR TECHNOLOGY LTC6240 LTC6241 LTC6242 Data Sheet User Guide
Summary
These advanced Operational Amplifiers are a series of single, dual, or quad low-noise Op Amps designed for high-precision signal processing applications. Featuring ultra-low input bias current (1pA max), rail-to-rail outputs, and exceptionally low offset voltage, they maintain stable performance even in demanding environments. Ideal for sensitive front-end electronics, medical instrumentation, and photodiode amplifiers requiring both rapid speed (up to 18MHz) and minimal noise across wide temperature ranges.
