Rotary encoder mates with digital potentiometer: 02/06/03 EDN Design Ideas / (added 1/05) In developing
electronic systems, designers look for products or ideas that may benefit from the better performance, smaller size, lower cost, and improved reliability that an IC can offer. Toward that end,
the digital potentiometer emerged as an alternative to its mechanical counterpart, the mechanical potentiometer.... |

Single Switch Controls digital potentiometer #1: 02/07/02 EDN - Design Ideas / (Electronic circuit added 10/03)
The control of electronic potentiometers in most today's applications comes from controller-generated signals. However, a significant number of applications exist that require adjustments
using manual, front-panel controls. The circuit in Figure 1 uses one IC, one switch, and 10 discrete components. . |

Single Switch Controls digital potentiometer #2: 09/19/02 EDN - Design Ideas / (Electronic circuit added 10/03)
This Design Idea is an evolution and simplification of another (Figure 1, Reference 1). Replacing the three inverted-input NOR gates with their logical equivalents, positive-input NAND gates,
makes these three gate symbols consistent with the fourth, which was drawn as a positive-input NAND gate. The 74HC132's data sheet describes the device as a quad, two-input NAND gate with
hysteresis.. |

Voltage Regulator goes Digital: 11/24/99 EDN-Design Ideas / (Electronic circuit added 5/02) - Power consumption and failing
batteries are key issues in battery-operated applications. Features in the new generation of series voltage regulators address these concerns. For example, National Semiconductors LP2951
MicroPower voltage regulator provides a logic-level output signal indicating a low regulated output voltage; the IC also has a logic-level input to shut down the regulator to conserve power. |

Where is the Wiper?: 08/08/02 EDN Design Ideas / (added 1/05) You enjoy significant advantages when using
DPPs (digitally programmable potentiometers) with increment/decrement serial interfaces. Programming the serial interface is simple and fast, and you can adjust the potentiometer in real-time
applications. The interface, however, provides no information about wiper position, and this information is important in some applications.... |
