OPA644中文资料Low Distortion Current Feedback OPERATIONAL AMPLIFIER数据手册TI规格书

描述 Description

DESCRIPTION
The OPA644 is a wideband precision current feed back operational amplifier featuring exceptionally high open loop transimpedance and high slew rate. The current feedback architecture allows for excellent large signal bandwidth, even at high gains. The high transimpedance allows this op amp to be used in applications requiring 16 bits or more of accuracy.FEATURES
