Processor's PWM output Controls LCD/LED Driver: 05/27/04 EDN Design Ideas / (added 1/05) The PWM
(pulse-width-modulation) output available from many microprocessors is based on an internal 8- or 16-bit counter and features a programmable duty cycle. It is suitable for adjusting the output of
an LCD driver, a negative-voltage LCD driver, or a current-controlled LED driver. cost alternative that provides not only a 4- to 20-mA output, |

PWM ADC is Surprisingly Accurate: 06/09/94 EDN-Design Ideas / (Electronic Circuit diagram added 03/03) The reference voltage
in Fig 1a's simple rail-to-rail PWM ADC is the only critical component. The input-voltage range extends from ground to the power rail which also acts as the reference. The circuit is essentially a
variation on the classic dual-slope integrator, the slopes being proportional to VIN and VREF-VIN. The circuit works well in µP-based systems that have the spare capacity to perform the mark/space
measurement and the necessary calculations..... |
