Texas Instruments DRV2700 工业压电驱动器
德州仪器 DRV2700 工业压电驱动器是一款单芯片压电驱动器,集成有 105V 升压开关、功率二极管和全差分放大器。这款多用途器件能够驱动高压和低压压电负载。输入信号可以是差分信号,也可以是单端信号,而且交流或直流耦合均支持。DRV2700 支持四种由 GPIO 控制的增益:28.8dB、34.8dB、38.4dB 和 40.7dB。升压转换器架构可防止电源电流超出由 R(REXT) 电阻设置的限值,这样用户便可以根据目标性能需求针对给定电感来优化 DRV2700 电路。此外,该升压转换器基于磁滞架构,可最大程度降低开关损耗,从而提高效率。特性
