Transcription

1 Micro-Power, RRIO, 1.V, Push-Pull Output GENERAL DESCRIPTION The is a low power comparator with a typical power supply current of 2.2µA. It features an uncommitted on-chip voltage reference, comparator input common mode range of mv beyond the supply rails, and single-supply operation from 1.V to 5.5V. The integrated 1.2V series voltage reference offers low 42µV/ drift, is stable with up to 1nF capacitive load, and can source up to 2mA (TYP) of output current. Designed to operate over a wide range of supply voltages, from 1.V to 5.5V, with guaranteed operation at 1.V and 5., the is ideal for use in a variety of battery-powered applications. With rail-to-rail input common mode voltage range, the is well suited for single-supply operation. Its small packages make this device ideal for use in handheld electronics and mobile phone applications. Featuring a push-pull output stage and having a latch enable input (LE ), the allows for operation with absolute minimum power consumption when driving any capacitive or resistive load. FEATURES Low Power Consumption: 2.2µA (TYP) at V S = 1.V Wide Supply Voltage Range: 1.V to 5.5V Push-Pull Output Current Drive: 1mA (TYP) at Rail-to-Rail Input Latch Function Included Integrated 1.2V Voltage Reference -4 to +5 Operating Temperature Range Available in Green SOT-23-6, SOT-23- and SOIC- Packages APPLICATIONS RC Timers Window Detectors IR Receiver Multivibrators Alarm and Monitoring Circuits is available in Green SOT-23-6, SOT-23- and SOIC- packages. It is rated over the -4 to +5 temperature range. REV. A. 1

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. CAUTION This integrated circuit can be damaged by ESD if you don t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time.
