Maxim Integrated MAX44248运算放大器

Maxim Maxim MAX44248运算放大器在较宽的供电范围内保持非常低的功耗。器件集成了获得专利的自动调零电路，可连续测量、补偿输入失调，从而消除随时间、温度变化产生的漂移以及1/f噪声的影响。器件还集成了EMI滤波器，以减小输出信号上的高频解调。该运算放大器采用2.7V至36V单电源供电，或±1.35V至±18V双电源供电。器件为单位增益稳定，具有1MHz增益带宽积，每路运放仅消耗90µA电流。低失调电压、低噪声以及较宽的供电范围，使得这Maxim MAX44248适合用于传感器接口和发射器。

The op-amps operate from either a single 2.7V to 36V supply or dual ±1.35V to ±18V supply. The devices are unity-gain stable with a 1MHz gain-bandwidth product and a low 90µA supply current per amplifier. The low offset and noise specifications and high supply range make the Maxim MAX44248 ideal for sensor interfaces and transmitters.
