Centronics Port D/A converters & low-pass
filter - JDAC and CENT_DAC are both simple Digital to
Analogue converter to use with your IBM PC/AT or compatible. Those circuit are connected to Centronics parallel
port and does not affect the normal port usage in any way. The circuits are transparent to computer, so it is not
possible to program to see if those devices are connected or not.. . . [Designed by Tomi Engdahl]

Circuit Loads Eight-Channel DAC from PC Port - 08/03/95 EDN Design Idea The circuit in Fig 1 loads 4 address bits and 8 data bits into
IC8's 8-bit octal, two-quadrant multiplying DAC from a PC parallel port. Initially, the circuit loads the desired
data on the D0 through D7 pins of the parallel port . . . [by Daniel Segarra, Sipex Corp, Billerica, MA]
Circuit maximizes pulse-width-modulated DAC throughput - 03/22/13 EDN Design Idea This ramp-based DAC uses microcontroller-generated clocks and a
sample-and-hold. Simple DACs realized by lowpass filtering microcontroller-generated pulse-width-modulated (PWM)
signals have a response that is typically a tenth of the PWM frequency. This Design Idea is a novel
implementation of a previously published method1 employing a reference ramp whose output is sampled and held by
the PWM signal. This approach results in a throughput rate equal to the PWM frequency. . . . [by Ajoy Raman]
CMOS DACs Act As Digitally Controlled Voltage Dividers - 06/26/08 EDN Design Idea You can employ a DAC to operate as a digitally programmable
resistor from a single supply. . . [by John Wynne and Liam Riordan, Analog Devices, Limerick, Ireland]
