DESCRIPTION
The THS3001 is a high-speed current-feedback operational amplifier, ideal for communication, imaging, and
high-quality video applications. This device offers a very fast 6500-V/μs slew rate, a 420-MHz bandwidth, and
40-ns settling time for large-signal applications requiring excellent transient response. In addition, the THS3001
operates with a very low distortion of –96 dBc, making it well suited for applications such as wireless
communication basestations or ultrafast ADC or DAC buffers.
