Inverter: Have you ever wanted to run a TV, stereo or other appliance
while on the road or camping? Well, this inverter should solve that problem. It takes 12 VDC and steps it up to 120 VAC. The wattage depends
on which tansistors you use for Q1 and Q2, as well as how "big" a transformer you use for T1. The inverter can be constructed to supply
anywhere from 1 to 1000 (1 KW) watts. (schematic / circuit added 10/06)
Make a DAC with a Microcontroller's PWM Timer: 09/05/02
EDN Design Ideas / (added 02/05) Many embedded-microcontroller applications require generation of analog signals. An
integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required analog signals. You can use
PWM signals to create both dc and ac analog signals. This Design Idea shows how to use a PWM timer to simultaneously create a sinusoid, a
ramp, and a dc voltage..
Mixed Signal Circuit Technologies: AN-280 Analog Devices Application
Notes (app note added 2/06) Considers problems which arise when reality (& Murphy) intervene in a design which
otherwise seems satisfactory in terms of theory and modeling.
Multiphase DAC Modifies R 2r Ladder: 01/18/96 EDN-Design
Ideas / (added 08/05) The double-ladder DAC in Figure 1 suits ASIC or hybrid designs that require multiple DACs
sharing an analog input but with different digital inputs and multiple analog outputs. The circuit is a modification of the standard R-2R
resistive ladder in a CMOS multiplying DAC. The two DAC sections in Figure 1 share the longitudinal resistors and split the latitudinal
resistors in the ladder. A possible name for this approach is an "R-4R" multiplying DAC (MDAC). (09/05)
