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) |
