Transcription

1 SGM87 Micro-Power, CMOS Input, RRIO, 1.4V, GENERAL DESCRIPTION The SGM87 is a dual low power comparator with a typical power supply current of 3nA (per channel). It has the best-in-class power supply current versus propagation delay performance. The propagation delay is as low as 6μs with 1mV overdrive at 1.4V supply. Designed to operate over a wide range of supply voltages, from 1.4V to.v, with guaranteed operation at 1.4V, 2.V and.v, the SGM87 is ideal for use in a variety of battery-powered applications. With rail-to-rail common mode voltage range, the SGM87 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, the SGM87 allows for operation with absolute minimum power consumption when driving any capacitive or resistive load. FEATURES Ultra Low Power Consumption: 3nA/Channel (TYP) at Wide Supply Voltage Range: 1.4V to.v Propagation Delay: 6μs (TYP) at Push-Pull Output Current Drive: 19mA (TYP) at Rail-to-Rail Input -4 to Operating Temperature Range Available in Green SOIC-8 and MSOP-8 Packages APPLICATIONS RC Timers Window Detectors IR Receiver Multivibrators Alarm and Monitoring Circuits SGM87 is available in Green SOIC-8 and MSOP-8 packages. It is rated over the -4 C to +8 C temperature range. REV. A. 2

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.
