LMP92018 is a complete analog monitoring and control circuit which integrates an eight channel 10-bit Analog-to-Digital Converter (ADC), four 10-bit Digital-to-Analog Converters (DACs), an internal reference, an internal temperature sensor, a12-bit GPIO port, and a 10MHz SPI interface.

The eight channels of the ADC can be used to monitor rail voltages, current sense amplifier outputs, health monitors or sensors while the four DACs can be used to control PA (Power Amplifier) bias points, control actuators, potentiometers, etc.

Both the ADC and DACs can use either the internal 2.5V reference or an external reference independently allowing for flexibility in system design.

The built-in digital temperature sensor enables accurate (±2.5°C) local temperature measurement whose value is captured in the user accessible register.

The LMP92018 also includes a 12-bit GPIO port which allows for the resources of the microcontroller to be further extended, thus providing even more flexibility and reducing the number of signal interfacing to the microcontroller.

Both the GPIO port and the SPI compatible interface have independent supply pins enabling the LMP92018 to interface with low voltage microcontrollers.

The LMP92018 is available in a space saving 36-pin WQFN package and is specified over the full -30°C to +85°C temperature range.
