Startup Requirements for the MAX1452/MAX1455 Sensor Signal Conditioners
The MAX1452 and MAX1455 are high-performance signal conditioners for sensors with analog voltage output. The signal conditioners can operate in both digital and analog modes. Typically, digital mode is used during transducer calibration, and the conditioner starts and operates in analog mode in the actual application. For a reliable startup in analog mode, the VDD and VDDF supplies must meet certain timing and profile requirements. This application note discusses these startup requirements, and gives guidelines for successful application of the devices.
