MSP430FR2355 microcontrollers

MSP430FR2355 MCUs integrate four configurable signal-chain modules called smart analog combos, each of which can be used as a 12-bit DAC or a PGA to meet system needs. 

MSP430FR2355 LaunchPad development kit

The MSP-EXP430FR2355 LaunchPad kit is based on the MSP430FR2355 MCU with 32KB of memory, four configurable smart analog combo modules (12-bit DACs and PGAs), a 12-bit ADC and two comparators.

Temperature transmitter reference design

Low-component count, low-cost solution for 4- to 20-mA loop-powered, resistance-temperature detector (RTD), temperature transmitter. 

Smart analog combo

The Smart Analog Combo is a configurable analog peripheral that includes a high-performance, low-power programmable gain amplifier (PGA) with gain up to 33 and a 12-bit digital-to-analog converter (DAC).

Benefits of smart analog combo

Reduced system size and cost

  • Up to four smart analog combo modules
  • Each module can be configured to be a 12-bit DAC, PGA or Op Amp
  • Smaller PCB outline

Easy to use

  • Straightforward software configuration
  • Can be changed on the fly
  • LaunchPad™ development kit with out-of-box demo and GUI

A wide variety of applications including:

  • Smoke and heat detectors
  • Temperature transmitters
  • Pulse oximeters
  • Gas or air quality detectors

Transimpedance amplifier (TIA)

The integrated transimpedance amplifier (TIA) is a high-performance low-power rail-to-rail output operational amplifier (Op Amp) configured to convert current to voltage.
