LTC1541/LTC1542 Micropower Op Amp, parator and Reference Features s s s s s s s s s DESCRIPTION The LTC®1541/LTC1542 bine a micropower amplifier, parator and bandgap reference (LTC1541) in an 8-pin package. The part operates from a single 2.5V to 12.6V or dual ± 1.25V to ± 6.3V supply with a typical supply current of 5µA. Both the op amp and parator feature a mon mode input voltage range that extends from the negative supply to within 1.3V of the positive supply. The op amp output stage swings from rail-to-rail. The parator’s inverting input is internally connected to the reference output (LTC1541). The reference output voltage is 1.2V ± 1% over the extended temperature range. The output can drive a bypass capacitor of up to 0.01µF without any oscillations. It can also source up to 2m A and sink up to 20µA. The op amp is internally pensated to be unity-gain stable with typical GBW at 12k Hz and slew rate of 8V/ms. The parator has ± 3m V of internal hysteresis to ensure clean output switching, even with slow moving input signals. The LTC1541/LTC1542 are available in MSOP and SO-8 packages. , LTC and LT are registered trademarks of Linear Technology Corporation. s s s s Quiescent Current: 5µA Typ Outputs Swing Rail-to-Rail Low Op Amp Offset Voltage: 700µV Max Reference Output Drives 0.01µF Capacitor Internal 1.2V ± 0.4% Reference Output (LTC1541) Low Input Bias Current: 1n A Max Reference Output Can Source Up to 2m A Internal ± 3m V parator Hysteresis parator and Op Amp Input Range Includes Ground Op Amp Capable of Driving Up to 1000p F Load Unity-Gain Stable and 12k Hz Bandwidth 2.5V to 12.6V Supply Voltage Range Daisy-Chained Control Outputs Pin patible Upgrade for MAX951/MAX953 U APPLICATIONS s s s s s s 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 TYPICAL APPLICATION Pilot Light...
