Question asked by lynnshaw on Nov 3, 2016

Here is what I am looking for: I need a low frequency (less than 10kHz) driver, which can drive the 50Ohms DC couple resistor in the testing instruments (like spectrum analyzer, oscilloscope). I found some parts, like ADA4940-1. When I checked its datasheet, I found the x-axis (frequency) only reaches 0.1MHz, which is still larger than what I need. Would you kindly help me out please and let me know if it can work well with that and is there other better options?
