The automotive-qualified LMP8480-Q1 and LMP8481-Q1 devices are precision, high-side, current-sense amplifiers that amplify a small differential voltage developed across a current-sense resistor in the presence of high input common-mode voltages. These amplifiers are designed for bidirectional (LMP8481-Q1) or unidirectional (LMP8480-Q1) current applications and accept input signals with a common-mode voltage range from 4 V to 76 V with a bandwidth of 270 kHz. Because the operating power-supply range overlaps the input common-mode voltage range, the LMP848x-Q1 can be powered by the same voltage that is being monitored. This benefit eliminates the need for an intermediate supply voltage to be routed to the point of load where the current is being monitored, resulting in reduced component count and board space.

The LMP848x-Q1 family consists of fixed gains of 20, 60, and 100 for applications that demand high accuracy over temperature. The low-input offset voltage allows the use of smaller sense resistors without sacrificing system error. The LMP8480-Q1 and LMP8481-Q1 are pin-for-pin replacements for the MAX4080 and MAX4081 devices, offering improved offset voltage, wider reference adjust range, and higher output drive capabilities. The LMP8480-Q1 and LMP8481-Q1 are available in an 8-pin VSSOP package.

The MSP-EXP430FR2355 LaunchPad Development Kit is an easy-to-use evaluation module (EVM) based on the MSP430FR2355 Value Line microcontroller (MCU). It contains everything needed to start developing on the ultra-low-power MSP430FR2x Value Line MCU platform, including on-board debug probe for programming, debugging and energy measurements. The board includes 2 buttons and 2 LEDs for creating a simple user interface. It also has an ambient light sensor and connector for external analog sources.

The MSP430FR2355 MCU includes a smart analog combo of configurable signal chain elements including options for multiple 12-bit digital-to-analog converters (DACs) and programmable gain amplifiers (PGAs) along with a 12-bit analog-to-digital converter (ADC) and two enhanced comparators (eCOMPs). One of the out-of-box demos includes a GUI to showcase some of the smart analog combo configurations.

The 24MHz MSP430FR2355 device features 32KB of embedded FRAM (Ferroelectric Random Access Memory), a non-volatile memory known for its ultra-low power, high endurance, and high-speed write access. Combined with the 4KB of on-chip SRAM, users have access to 32KB of memory to split between their program and data as required. For example, a data logging application may require a large data memory with a relatively small program memory, so the memory may be allocated as required between program and data memory.

Features:

• ULP FRAM technology based on the MSP430FR2355 16-bit MCU with smart analog combo
• On-board eZ-FET debug probe with EnergyTrace Technology available for ultra-low-power debugging
• 40-pin LaunchPad headers to leverage the BoosterPack ecosystem
• 2 buttons and 2 LEDs for user interaction
• On-board ambient light sensor
• On-board Grove module interface to add external sensors, actuators and more
