DESCRIPTION
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.
