PRODUCTION DATA.
The TLC694x device can adjust the brightness of each output channel using a pulse-width-modulation (PWM) control scheme. The architecture of 16 bits per channel results in 65536 brightness steps, from 0% up to 100% brightness. The on-time (tOUT_ON) of each output (OUTn) can be calculated by Equation 2.
where
The TLC694x device implements an enhanced spectrum (ES) PWM control. The ES-PWM control can be selected with two different modes: 8-bit MSB + 8-bit LSB (8+8) mode, and 9-bit MSB + 7-bit LSB (9+7) mode. See TLC6946 Technical Reference Manual for more details.
