产品概述 返回TOP
The CXCO4311 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 200mV beyond the supply rails, and single-supply operation from 1.8V to 5.5V. The integrated 1.2V series voltage reference offers low 42μV/℃ drift, is stable with up to 10nF capacitive load, and can source up to 2mA (TYP) of output current.
Designed to operate over a wide range of supply voltages, from 1.8V to 5.5V, with guaranteed operation at 1.8V and 5.0V, the CXCO4311 is ideal for use in a variety of battery-powered applications. With rail-to-rail input common mode voltage range, the CXCO4311 is well suited for single-supply operation. Its small package makes this device ideal for use in handheld electronics and mobile phone applications.
The CXCO4311 has a push-pull output stage. CXCO4311 is available in Green UTDFN-1.6×1.6-6L package. It is rated over the -40℃ to +85℃ temperature range.
