LTC1541CS8#PBF

LTC1541 is a combination of micropower amplifier, comparator and bandgap reference. The op-amp output stage swings from rail-to-rail. The comparator’s inverting input is internally connected to the reference output. The reference output voltage is 1.2V ±1% over the extended temperature range. The output can drive a bypass capacitor of upto 0.01µF without any oscillations. It can also source upto 2mA and sink upto 20µA. It is widely used in application such as battery- or solar-powered systems, automotive keyless entry, low frequency, local area alarms/detectors, infrared receivers for remote controls, smoke detectors and safety sensors, GSM portable phones etc.
