The LMC6044IM/NOPB is a CMOS quad MicroPower Operational Amplifier for use with fire and smoke detection systems. Ultra-low power consumption and low input-leakage current are the hallmarks of the LMC6044. The LMC6044 can operate from a single supply, has output swing extending to each supply rail and an input voltage range that includes ground. It is ideal for use in systems requiring ultra-low power consumption. In addition, the insensitivity to latch-up, high output drive and output swing to ground without requiring external pull-down resistors make it ideal for single-supply battery-powered systems. Other applications for the LMC6044 include bar code reader amplifiers, magnetic and electric field detectors and hand-held electrometers. This device is built with National's advanced double-poly silicon-gate CMOS process.
