TILMP92018SQ/NOPB
Overview
The LMP92018SQ/NOPB is a highly integrated analog system monitor and controller designed for complex system management. It combines an 8-channel, 10-bit ADC with a 4-channel, 10-bit DAC and 12 programmable GPIO pins into a single 36-pin WQFN package. This device serves as a centralized node for monitoring voltages and controlling analog subsystems via a standard SPI interface.
Why Choose This Part
This controller offers significant board space savings by consolidating ADC, DAC, and GPIO functions into a 6x6mm footprint. It features an internal 2.5V reference for simplified design and supports high-source impedance inputs, making it resilient when monitoring various signal types. Each bit is individually programmable, providing engineers with high flexibility for customized system logic.
Applications
Key Specifications
Getting Started
Designers should interface the LMP92018SQ/NOPB with a microcontroller via the SPI bus and ensure the 4.75V to 5.5V supply is adequately decoupled. Evaluation of the internal 2.5V reference versus an external source is recommended based on specific accuracy requirements. The thermal pad on the 36-WQFN package must be properly soldered to the PCB ground plane for both electrical and thermal performance.
