Buffer adapts single ended signals for differential inputs - 09/02/04 EDN-Design
Ideas: DC coupling of single-ended signals into differential-input, single-supply ADCs
can be challenging. The input signal requires level shifting from ground to VS/2 as
well as single-ended-to-differential conversion. In addition, you must balance the
differential inputs of the ADC to cancel even-order harmonics and common-mode
noise.....(design idea added 1/05) |

Control 32 DAC Channels via a Parallel Port - 07/08/99 EDN-Design Ideas: [Note:
File contains multiple circuits. Scroll to find this one.] Occasionally, a
system needs several digitally programmable voltage-output channels. Such output
channels typically provide the control for robot positioning, industrial processes,
and even home automation. The circuit in Figure 1 controls 32 voltage-output channels
from the parallel port of a PC. The circuit comprises eight DAC7615 quad
voltage-output, serial-data programmable, 12-bit DACs. The controlling PC individually
programs each of the 32 DAC channels, and all DAC outputs simultaneously
update.....(design idea added 11/05) |

in hardware. The multiplying DAC in Fig 1 performs the windowing of an input

DAC & OpAmp Provide Variable Control Voltage - 12/06/01 EDN-Design Ideas: Early
DACs contained standard R-2R ladder networks, and produced a negative output voltage.
These early DACs, such as the MAX7837/7847 and the MAX523, require both positive and
negative supply rails to accommodate their negative output. With the transition to
single-supply ICs, however, many modern DACs operate with a single supply rail and an
inverted R-2R ladder network.....(design idea added 6/06) |

DDS IC Plus Frequency to Voltage Converter Make Low Cost Dac - 02/05/04 EDN-Design
Ideas: Precision DACs are essential in many consumer, industrial, and military
applications, but high-resolution DACs can be costly. Frequency-to-voltage converters
have good nonlinearity specifications—typically, 0.002% for the AD650—and are
inherently monotonic. This Design Idea shows how you can use a frequency-to-voltage
converter and a DDS (direct-digital-synthesizer)chip for precise..... You can
effectively double the sample rate of a DAC by interleaving two DACs into a single
unit. Updating each DAC on an alternating basis and switching to the appropriate
output double the effective throughput of the overall system. It is essential to
overall performance that you use a high-quality, high-speed switch in the multiplexing
of the DACs' outputs. (added 10/05) |

Designing High Current Chokes is Easy - 06/24/04 EDN-Design Ideas: Somewhat
unusually, this Design Idea deals with a formula rather than a circuit. You might
think that all the basic formulas of magnetic phenomena were discovered more than a
century ago. In fact, they probably were, but, at the time, some were of little
practical interest and were essentially disregarded and never included in books or
formula tables.....(design idea added 02/05) |

Designing High Current Vrm Compliant CPU Power Supplies - 10/26/00 EDN-Design
Ideas: Modern high-speed microprocessors require fast delivery of enormous supply
currents in microsecond time frames, tight supply-voltage tolerance, and intelligent
voltage programming. The latest CPU voltage-regulator specifications from Intel and
AMD call for load-current slew rates of 50 to 200A/µsec and peak currents of 60 to
more than 120A. These demands are transforming the design of portable power supplies
to levels almost like those of utility power. The core supply voltage of the CPU must
remain within its specified tolerance even when the processor performs a current-load
step from nearly 0 to more than 60A in a few microseconds. This process requires a
proper design approach and knowledge of advanced power.....(design idea added 5/05) |
