Bob's Mailbox
Dear Bob: I really enjoyed your piece (and your articles in general) on Analog PowerPoint.* It gave me a chuckle and reminded me of my own experience. I was invited to speak at the TAPR conference about CIRCAD (a CAD program). Before I...
What's All This Cruise Control Stuff, Anyhow?
Okay, Pease. You brag that you can slap together a good breadboard in an hour or two, all hay-wired over a copper-clad ground plane. How come it took you two years to build this circuit? Well, most breadboards are quick to build, and...
PC/104 SBC Gets Analog Data
The Athena HRC104 PC/104 single-board computer (SBC) from Diamond Systems couples a low-power, 660-MHz Via Eden x86-compatible processor with a data-acquisition controller that sports a 16-channel, 16-bit analog-to-digital converter and four-channel,...
High-Performance 14-Bit DAC Zips Along At 1.2 Gsamples/s
The AD9736 14-bit, 0.18-µm CMOS current-output digital-to-analog converter (DAC) breaks the 1-Gsample/s barrier with a 1.2-Gsample/s rate at a 316-MHz output. And, it does so without compromising performance and at a low power dissipation of 380...
24-Bit IC Delivers Total, Precision Data Acquisition
By integrating analog and digital cores on the same piece of silicon, the Burr-Brown Division of Texas Instruments created a low-cost and high-performance precision data-acquisition system-on-a-chip. The MSC1200 delivers performance levels for in...
Comm Techniques Yield All-Digital High-Power Audio Amp
Virtually every electronic product today is digital, including products in the once all-analog domain of communications. Audio power amplification is about the last thing to be digitized. And thanks to communications techniques, D2Audio has created...
Trimmable Analog IP Blocks Come Fully Armed With Power Management
A new weapon in the arsenal for designers of Bluetooth and Wi-Fi (802.11) system-on-a-chip (SoC) ICs provides low-cost, ultra-accurate trimming of nearly all power-management circuits. By leveraging its know-how in accurately laser-trimming CMOS...
80-Msample/s 14-Bit ADC Takes On 500-MHz Inputs
It's crucial for cellular basestation designers to get the most dynamic performance out of their components. A new option, the LT1750 14-bit analog-to-digital converter (ADC) from Linear Technology, samples at 80 Msamples/s while accepting input...
Current-Output 14-Bit DAC Squeezes Into Tiny SOT-23
If you need a wide-bandwidth, current-output digital-to-analog converter (DAC) where space is at a premium, try the AD5453. This 14-bit current-output multiplying device comes in a tiny SOT-23 package that measures 2 by 2 mm and has a multiplying...
Bob's Mailbox
Dear Bob: I designed magnetic stripe readers in the eighties and would like to comment on your recent "Bob's Mailbox."* Three tracks are defined on the standard card. Most credit, ATM, and debit cards use track two in the middle of the stripe....
1.6-GHz 8-Bit ADC Consumes Just 1.4 W
With a 1.6-GHz sampling rate at 8 bits of resolution and a 1.4-W power dissipation from a 1.9-V supply, the ADC018000 8-bit analog-to-digital converter (ADC) is primed for test-and-measurement and communications applications. At a 100-MHz input and...
Optical System Stumps Identity Thieves
Thanks to an analog authentication process, the OptiKey verification system raises identification technology to a new level by creating a unique signature in a submicron optical master. The optical master signature is then embedded in the ID label....
Analog/Power: Space-Saving 30-V MOSFETs Make Automotive Grade
A quartet of 30-V n-channel MOSFETs is qualified to the AEC-Q101 standard, a reliability test qualification procedure for automotive uses. The FDD044AN03L, FDU044AN03L, FDD068-AN03L, and FDU068AN03L come in both TO-252 and TO-251 packages for...
Analog/Power: Bipolar Transistors Take Saturation Voltage To Next Level
Thanks to advances in material technology, the Generation 5 series bipolar transistors offer reductions in component resistance that in turn deliver a 30% gain in VCE(SAT) compared with previous generations. The initial series covers a...
Analog/Power: Triple Video Amp With Gain Of 2 Delivers Sharp Image Quality
A fast slew rate of 2500 V/µs coupled with a quick 6-ns settling time enables the LT6553, a triple video amplifier with internally fixed gain of 2, to offer enhanced ac performance that yields sharper video images. The device's 0.01°...
Embedded: 12-Bit Analog Input Comes Through USB
The PMD-1208LS provides eight channels of 12-bit analog data via a USB connection. It has a 1.2-ksample/s rate or 8 ksamples/s, but data is limited to 4000 samples. The unit also has a 32-bit timer, a pair of 10-bit analog outputs, and 16 digital...
"Arm"-ing Analog Microcontrollers
Standard Arm-based products are quickly becoming the standard for midrange microcontrollers (MCUs). Analog Devices' ADuC702x family puts these products in the middle of analog space. It's not surprising, given Analog's previous endeavors with its...
Analog Front-End IC Presents Total Motor-Control Solution
High throughput and simultaneous sampling for multi-axis positioning, motion control, and robotics come via the ADS7869 IC, a complete analog front end for motor-control applications. This Texas Instruments device integrates three 12-bit, 1-Msample/s...
Working With Analog/Mixed Signals
Sponsored by: NATIONAL SEMICONDUCTOR
Signal conditioning often consists of converting an analog signal from a sensor in the physical world into a digital signal that can be used for data collection, controlling a process, performing calculations, producing display readouts, and other...
Variable-Gain Amplifiers: A Look At The Larger Picture
Programmable-gain ampliifers (PGAs) are actually a subset of variable-gain amplifiers (VGAs). Widely used in wireless communications, industrial scanning, radar, ultrasound, and speech-analysis applications that require a wide dynamic range of...
