Texas Instruments TPS8804EVM AFE Evaluation Module (EVM)

Texas Instruments TPS8804EVM AFE Evaluation Module (EVM) is used to evaluate the TPS8804 smoke and CO detection analog front end and power management IC. The evaluation module allows for easy connection from the TPS8804 to a user-supplied photoelectric chamber and carbon monoxide sensor. The TPS8804 GUI interfaces with the evaluation module to quickly evaluate the photo amplifier, LED driver, and CO amplifier performance, as well as static system power consumption. For a more thorough evaluation, an external microcontroller can be connected to the evaluation module to create a prototype smoke detection system.

Features

  • Dual LED drivers for blue and IR LEDs
  • Wide bandwidth, low offset photodiode amplifier
  • Ultra-low-power CO transimpedance amplifier
  • LDOs for internal analog blocks and external microcontroller
  • Single buffered analog output AMUX for CO and photo signals
  • Serial interface for configuring amplifiers, drivers, regulators
  • SLC interface for power line communication
  • Under-voltage, over-temperature fault monitors
  • Wide input voltage range for flexible power supply configuration

Required Equipment

  • 4.5V to 15.5V power supply capable of 100mA
  • USB2ANY™ interface adaptor
  • TPS880x GUI software
  • Multimeter for measuring regulator voltages and CO amplifier output
  • Oscilloscope for measuring photodiode signal pulse shape
