MAXIM INTEGRATED PRODUCTS  MAX4247AUB+  运算放大器, 轨至轨输入输出, 超小型, 1 MHz, 2个放大器, 0.4 V/µs, 2.5V 至 5.5V, ± 1.25V 至 ± 2.75V, µMAX, 10 引脚

The is an ultra small, low power, dual rail to rail I/O operational amplifier op-amp with disable function in 10 pin µMAX package. It is designed for low voltage and single supply operation. The input stage consists of composite NPN and PNP differential stages which operate together to provide a common mode range extending to both supply rails. This low cost op-amp draws only 320µA of quiescent current and operates from single 2.5V to 5.5V supply or dual ±1.25V to ±2.75V supplies. It offers a low power shutdown mode which reduces supply current to 50nA and puts amplifier outputs in a high impedance state. The MAX4247 is unity gain stable with 1MHz gain bandwidth product and driving capacitive loads up to 470pF. The wide operating temperature range makes this device suitable for use in variety of harsh environments. It is used in single supply zero crossing detectors, instruments and terminals, electronic ignition modules, infrared receivers and sensor signal detection.
