数据: Family of 1 uA/Ch Rail-to-Rail Input/Output Operational Amplifiers 数据表
TLV224x系列单电源运算放大器提供每通道仅1 uA的极低电源电流。
低电源电流与极低的输入偏置电流相结合,使它们能够与mega一起使用 - 电阻器使其成为便携式,长寿命应用的理想选择。低典型偏移电压低至600 uV,CMRR为100 dB,最小开环增益为100 V /mV(2.7 V),确保直流精度。
建议的最大电源电压高为12 V,确保工作电压低至2.5 V,电气特性指定为2.7 V,5 V和12 V. 2.5 V工作使其兼容锂离子电池供电系统和许多微功率微控制器,包括TI的MSP430 。
