TLC5947DAPR Frequently Asked Questions (FAQs)

  • The maximum frequency of the clock input is 25 MHz, but it's recommended to use a clock frequency between 10 kHz to 10 MHz for optimal performance.
  • To ensure proper initialization, apply a reset pulse to the RST pin, then send a GSCLK pulse to the GSCLK pin to set the grayscale clock frequency. After that, send a SIN pulse to the SIN pin to set the shift-in data.
  • The OUTGRP pin is used to group multiple TLC5947DAPR devices together to control a larger number of LEDs. It allows the devices to be connected in a daisy-chain configuration.
  • The brightness of the LEDs can be adjusted by changing the grayscale data sent to the device. The grayscale data is an 8-bit value that determines the brightness of each LED, with 0 being the darkest and 255 being the brightest.
  • The maximum current rating of the TLC5947DAPR is 120 mA per channel, with a total current rating of 1.44 A for all 16 channels.
