µC Controls Digital Potentiometer - 10/08/98 EDN-Design
Ideas....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....Several circuits in article, scroll to f ind this one.

16-bit adjustable reference uses 8-bit digital potentiometers -
25-Dec-03 Issue of EDN It may be easy to find a precision voltage
reference for your application; however, a programmable precision reference
is another matter. The circuit in Figure 1 yields a precision reference with
an LSB of 62.5 µV. The circuit is a 16-bit DAC using three 8-bit digital
potentiometers and three CMOS op amps.... [Design Idea by Bonnie Baker,

Add gain to an absolute-value amplifier - 22-Aug-02 Issue of EDN 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 another dimension, G (gain], to this key circuit. Because the gain
is programmable, you can use the circuit as an absolute-value amplifier (G&1] or an
absolute-value attenuator (G>1].... [Design Idea by Chuck Wojslaw, Catalyst
