Combine Two 8 Bit Outputs to Make One 16 Bit Dac:  09/30/04   EDN-Design Ideas / (added 5/05)  Inexpensive, 16-bit, monolithic DACs can serve almost all applications. However, some applications require unconventional approaches. This Design Idea design concerns circuitry I recently designed for a tunable-diode laser spectrometer for a Mars-exploration application. The control circuitry included two 16-bit DACs ....

Control 32 DAC Channels via a Parallel Port:  07/08/99 EDN Design Ideas  / (added 11/05) [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....

DAC and µP Implement Hardware Window Generator:  03/31/94 EDN-Design Ideas / (added 03/03) A typical DSP system first converts an analog signal to digital, then performs windowing, and finally does a fast-Fourier transform. However, you can accelerate this process by swapping the converting and windowing steps and implementing the windowing in hardware. The multiplying DAC in Fig 1 performs the windowing of an input signal and produces the following output signal, where the digital code N ranges from 0 to 4095: VOUT=-VIN(N/4096.... 

DAC and Op Amp Provide Variable Control Voltage:  12/06/01 EDN Design Ideas  /  (added 6/06)  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. ...

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......

Designing High Current Chokes is Easy:  06/24/04 EDN Design Ideas  /  (added 02/05)  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....

Designing High Current Vrm Compliant CPU Power Supplies:  10/26/00   EDN-Design Ideas / (added 5/05)   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....

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....

Dpps Make Nonvolatile MicroVolt Dac:  10/31/02 EDN Design Ideas  /  (added 2/05)  The availability of a seemingly limitless variety of monolithic DAC chips makes it easy to implement most digital-to-analog-conversion applications with a single off-the-shelf device. Sometimes, an unusual set of requirements necessitates a multichip approach, however. One example of such a requirement is the need for nonvolatility of the DAC's setting in power-up and -down cycles....
