美国国家半导体公司近日推出一款偏置电流低于所有竞争产品的高精度放大器LMP772。这款芯片在-40°C~125°C的温度范围内,其输入偏置电流只有20fA,因此可大幅提高光电二极管及高阻抗传感器的系统灵敏度及准确度。LMP7721芯片是PowerWise系列的最新型号产品,该芯片仅用1.3mA电流
National Semiconductor recently introduced a high-precision amplifier LMP772 bias current lower than all competing products. The chip’s input bias current is only 20fA over the -40 ° C to 125 ° C temperature range, dramatically improving the system sensitivity and accuracy of photodiodes and high-impedance sensors. The LMP7721 chip is the latest addition to the PowerWise family and uses only 1.3mA of current
