AD7124-4BCPZ-RL7

AD7124-4 is a low power, low noise, completely integrated analogue front end for high precision measurement application. The on-chip low gain stage ensures that signals of small amplitude can be interfaced directly to the ADC. One of the major advantages of the device is that it gives the user the flexibility to employ one of three integrated power modes. The current consumption, range of output data rates, and rms noise can be tailored with the power mode selected. The device also offers a multitude of filter options, ensuring that the user has the highest degree of flexibility. The device establishes the highest degree of signal chain integration. The device contains a precision, low noise, low drift internal band gap reference, and also accepts an external differential reference, which can be internally buffered. It is widely used in application such as temperature measurement, pressure measurement, industrial process control, instrumentation, smart transmitters etc.
