Maxim has developed two high-integration products targeting Factory Automation, the MAX78638
. The MAX78638 is a turnkey solution for 3-phase motor energy measurement and diagnostics, allowing for constant and simultaneous monitoring of multiple pumps and motors. The instrument contains a microcontroller, compute engine, a high-accuracy ADC, and flexible and configurable sensor interfaces that allow for the measurement of current, voltage, speed, vibration, position and temperature. The MAX31865, touted as the industry's first fully integrated RTD-to-digital converter, is a single-chip solution to the common industrial design problem of digitizing a platinum RTD (such as a Pt100 or Pt1000) resistance, offering accurate measurement of temperature for industrial measurement and process control applications. Specified over the -40°C to 85°C temperature range, pricing for the MAX78638 starts at $6.13 each/1000. Limited sampling of the MAX31865 is available now with production slated for mid-November. Packaged in a 5 x 5 mm, 20-pin TQFN, pricing for the MAX31865 starts at $3.00 each/1000.
