CN2333SP8 資料下載

The CN333, CN2333, CN4333 families of products are CMOS operational amplifier offering very low offset voltage (2 μV typical) and near-zero drift over time and temperature. They have high-impedance inputs that have a common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within 50 mV of the rails. Single or dual supplies as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V) can be used. These devices are optimized for low-voltage, single-supply operation. The op-amps provide 350KHz bandwidth at a low current consumption of 15uA per amplifier, offering excellent CMRR without the crossover associated with traditional complementary input stages., making this device an excellent choice for sensor interface, active filter, low voltage or battery operated systems.
