  1. Marián Štofka EDN Analog Devices’ digitally gain-programmable AD8231 instrumentation amplifier exhibits zero offset. It has programmable voltage gains, which are successive powers of two, from 2 0 = 1 to 2 7 = 128. The AD825x ...

  2. Praveen K Electronic Design In certain applications, like pH measurement based on electromagnetic field (EMF) changes in an electrochemical reaction, the change in voltage is very small and the voltage range varies with the solution's ...
  3. John Wynne EDN When two different-metal conductors connect together in a loop and one of the junctions is at a higher temperature than the other, an electrical current flows through the loop. The magnitude of this current depends on the type of ...
  4. Marian Stofka EDN A capacitor that you charge through a resistor operates at 50% efficiency; hence, many engineers avoid using switched-capacitor dc/dc converters. That efficiency figure holds true only for capacitors with no initial voltage, ...

  5. Marián Štofka EDN Many applications require a sampling circuit whose output is inverted with regard to the respective sample of an input signal. A simple approach is a cascade of a common noninverting sample-and-hold amplifier and an ...
  6. Adolfo Garcia EDN The circuit in Figure 1 filters 60-Hz interference from low-frequency, low-level signals. The filter exhibits 40-dB rejection (Q = 0.75) and draws 95 uA max from a single-sided 5 V supply. Figure 1. This notch filter suppresses ...
  7. Kenneth Gustafsson EDN Some instrumentation amplifiers use external resistors to set their gain. Unfortunately, the lack of temperature-coefficient matching between the external and the internal resistors results in a high gain drift. If, however, ...
  8. Robert F. Coughlin Electronic Design Adding “intelligence” to measurement systems has become commonplace because 8-bit microcontrollers are inexpensive and widely available, and they can be programmed in many of today’s popular ...
  9. Moshe Gerstanhaber and Chau Tran, Analog Devices EDN Figure 1 shows two large-signal- measurement methods. The first uses a two-resistor voltage divider and an output buffer, and the second comprises an attenuating inverter and a high-value input ...
  10. Alan Stummer Electronic Design By using a constant-current source along with a ratiometric DAC configuration, the output intensity of a laser diode can be carefully set and controlled using this simple circuit. This circuit was designed to meet a ...
