The MAX9613/MAX9615 are low-power precision op amps with rail-to-rail inputs and rail-to-rail outputs. They feature precision MOS inputs powered from an internal charge pump to eliminate crossover distortion that is common to complementary input-pair type amplifier architectures. These devices are ideal for a large number of signal pro- cessing applications such as photodiode transimped- ance amplifiers and filtering/amplification of a wide variety of signals in industrial equipment.
The MAX9613 and MAX9615 are low‑power precision operational amplifiers with rail‑to‑rail inputs and outputs. They feature an internal charge‑pump‑powered MOS input stage that eliminates crossover distortion, making them suitable for photodiode transimpedance amplifiers, active filters, and a wide range of industrial and portable signal‑processing applications.
