Low-Power, low-voltage ADC is 0.05% linear -  06/19/97 EDN Design Idea   The simple integrating 3V A/D converter in Figure 1a is small, requires no negative supply and no expensive precision components, and draws minimal supply current. . . .  [by John Wettroth, Maxim Integrated Products, Sunnyvale, CA]

Make a DAC with a microcontroller's PWM timer -  09/05/02  EDN Design Idea   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 sig. . .  [by Mike Mitchell, Texas Instruments Inc]

Maximize 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]

Micropower ADC has eight differential channels -  05/22/97 EDN Design Idea   If you need a 12-bit ADC with eight differential channels for a portable, battery-powered data-acquisition system, you'll find that many 12-bit ADCs with configurable multiplexers are available. However, they all suffer from as much as 50% channel reduction when you require differential inputs. The circuit in Figure 1 overcomes the channel-reduction problem. It provides eight differential-channel, 12-bit A/D conversion. . . .  [by Kevin Hoskins, Linear Technology, Milpitas, CA]

Minimizing thermocouples maintains 20-bit DAC precision -  05/03/01  EDN Technical Article: Undesirable and unintended thermocouples are the primary sources of error in low-drift circuits. Attention to layout and other construction details is the only way to tackle the problem. . . .  [by Jim Williams, EDN's most revered contributor-At 63 years of age, Williams passed away in June 2011 after a stroke.]
