µC Controls Digital Potentiometer  - 10/08/98 EDN-Design Ideas: Several circuits in article, scroll to f ind this one.  Many digitally controlled potentiometers (for example, the LM1971/02/3 from National Semiconductor, www.national.com)incorporate a three-wire serial digital interface, using data, clock, and enable lines. In Figure 1, the potentiometer's nomenclature for these lines is Data-In.....(design idea added 11/05)

16 bit adjustable reference uses 8 bit Digital potentiometers - 12/25/03 EDN-Design Ideas: It may be easy to find a precision voltage reference for your application; however, a programmable precision reference is anor matter.  circuit in Figure 1 yields a precision reference with an LSB of 62.5 µV.  circuit is a 16-bit DAC using three 8-bit digital potentiometers and three CMOS op amps.....(design idea added 6/06)

Add gain to an absolute value Amplifier - 08/22/02 EDN-Design Ideas: The absolute-value amplifier is a basic building block in test-and-measurement and signal-processing applications. The addition of a DPP (digitally programmable potentiometer)adds anor dimension, G (gain), to this key circuit. Because  gain is programmable, you can use  circuit as an absolute-value amplifier (G<1)or an absolute-value attenuator (G>1).....(design idea added 1/05)
