The ADA4528-1/ADA4528-2 are ultralow noise, zero-drift operational amplifiers featuring rail-to-rail input and output swing. With an offset voltage of 2.5 μV, offset voltage drift of 0.015 μV/°C, and typical noise of 97 nV p-p (0.1 Hz to 10 Hz, AV = +100), the ADA4528-1/ADA4528-2 are well suited for applications in which error sources cannot be tolerated.

The ADA4528-1/ADA4528-2 have a wide operating supply range of 2.2 V to 5.5 V, high gain, and excellent CMRR and PSRR specifications, which make it ideal for applications that require precision amplification of low level signals, such as position and pressure sensors, strain gages, and medical instrumentation.

The ADA4528-1/ADA4528-2 are specified over the extended industrial temperature range (−40°C to +125°C). The ADA4528-1 and ADA4528-2 are available in 8-lead MSOP and 8-lead LFCSP packages.

For more information about the ADA4528-1/ADA4528-2, see the AN-1114 Application Note, Lowest Noise Zero-Drift Amplifier Has 5.6 nV/√Hz Voltage Noise Density.

Applications

  • Thermocouple/thermopile
  • Load cell and bridge transducers
  • Precision instrumentation

EVAL-CN0357-ARDZ

Arduino Compatible Electrochemical Gas Detection Circuit (CN0357)

Arduino Compatible Electrochemical Gas Detection Circuit (CN0357)

Features and Benefits

  • Form Factor Compatible with Arduino
  • Programmable for multiple other gases
  • Resolution down to 1ppm
  • Low power, single supply operation

Product Detail

CN0357 single-supply, low noise, portable gas detector circuit using an electrochemical sensor. The Alphasense CO-AX carbon monoxide sensor is used in this example. Electrochemical sensors offer several advantages for instruments that detect or measure the concentration of many toxic gases. Most sensors are gas specific and have usable resolutions under one part per million (ppm) of gas concentration.
