ADC Interface Conditions High Level Signals: 10/30/03 EDN
Design Ideas / (added 1/05) Designers who build
equipment for industrial market share a widespread problem. At one
extreme, y must build equipment that supports ±10V bipolar voltages,
often riding on a high common-mode level, a requirement enforced by 30
years of legacy industrial equipment. At or extreme, analog
signal needs conditioning to match full-scale range of a

Active Pullup/Pulldown
Network Saves Watts: 02/17/05 EDN Design Ideas / (added
5/05) The control circuit in Figure 1 presents a relatively low
input resistance and thus imposes a low value on external pulldown
resistor R1 to provide desired low-level input voltage. In turn,
R1 wastes power by drawing a relatively high current through switch S1.
For example, suppose that control circuit presents an input
resistance of 2. |

differential pulse-code-modulation (ADPCM) algorithm, you can now
implement se audio capabilities in low-cost 8-bit µCs, which typically
have lower power consumption and cost than ir DSP or audio-chip
counterparts. A two-chip design is feasible by offloading encoding
and decoding tasks onto µC as if it were a peripheral. Since 1991,
