Description
The ZL40166 is a low cost voltage feedback opamp
capable of driving signals to within 1V of the power
supply rails. It features low noise and low distortion
accompanied by a high output current which makes it
ideally suited for the application as an xDSL line driver.
The dual opamp can be connected as a differential line
driver delivering signals up to 18.8Vpp swing into a 25
Ω load, fully supporting the peak upstream power levels
for upstream full-rate ADSL (Asymmetrical Digital
Subscriber Line).
The wide bandwidth, high power output and low
differential gain and phase figures make the ZL40166
ideally suited for a wide variety of video driver
applications.
