Typical Application
Overview
The LMP92001 has a flexible, feature-rich functionality which makes it ideally suited for many analog monitoring
and control applications, for example base-station PA subsystems. This device provides the analog interface
between a programmable supervisor, such as a microcontroller, and an analog system whose behavior is to be
monitored and controlled by the supervisor.
To facilitate analog monitoring functionality, the device contains a single 12-bit ADC fronted by a 17-input
multiplexor. The 16 MUX inputs are available to the user via pins IN[16:1]. The last remaining MUX channel is
reserved for the internal analog temperature sensor.
