产品概述 返回TOP
The CXCO4309 is an ultra low power comparator with atypical power supply current of 318nA. It has the best-in-class power supply current versus propagation delay performance. The propagation delay is as low as 6μs with 100mV overdrive at 1.4V supply.
Designed to operate over a wide range of supply voltages, from 1.4V to 5.5V, with guaranteed operation at 1.4V, 2.5V and 5.0V, the CXCO4309 is ideal for use in a variety of battery-powered applications. With rail-to-rail input common mode voltage range, the CXCO4309 is well suited for single-supply operation. Its small packages make this device ideal for use in handheld electronics and mobile phone applications.
Featuring an open drain output stage, the CXCO4309 allows for operation with absolute minimum power consumption when driving any capacitive or resistive load.
CXCO4309 is available in Green SOT-23-5 and SC70-5 space-saving packages. It is rated over the -40℃ to +85℃ temperature range.
