• 16-bit, dual-channel ADCs span 20M to 80M samples/sec
  
  Author: by Paul Rako | Date: Jan 7, 2010
  Analog Devices' new AD9269 family of 20M-, 40M-, 65M-, and 80M-sample/sec pipeline ADCs takes 16-bit samples. The units consume 42 to 93 mW of power, depending on speed, and they integrate both a reference and a sample-and-hold circuit. The differential-input stage features a 700-MHz bandwidth, and

• Understanding CMR and instrumentation amplifiers
  
  Author: By Bonnie Baker | Date: Nov 26, 2009
  From the CMR (common-mode rejection) perspective, instrumentation amplifiers are systems in which various parts contribute to the CMR error at different system gains.
• Take a risk; throw away those bits!
  
  Author: By Bonnie Baker | Date: Oct 22, 2009
  You can create a 12-bit system using a 24-bit converter and eliminate the need for analog gain and level-shifting circuits.
• Create a DAC from a microcontroller's ADC
  
  Author: Vardan Antonyan, Glendale, CA; Edited by Martin Rowe and Fran Granville | Date: Dec 3, 2009
  Few microcontrollers include a DAC. Although you can easily find an inexpensive DAC to control from your microcontroller, you can use unused peripherals instead of adding parts.

• Circuit lets you test sample-and-hold amplifiers
  
  Author: Marián Štofka, Slovak University of Technology, Bratislava, Slovakia; Edited by Martin Rowe and Fran Granville | Date: Mar 4, 2010
  Sample-and-hold amplifiers sample an analog voltage and hold it until an ADC can digitize it. A perfect sampling circuit holds a voltage until digitizing is complete. Thus, the amplifier’s output is identical to its input.
