AD7171BCPZ-REEL7

AD7171 is a very low power, 16bit, analogue-to-digital converter (ADC). It contains a precision, 16bit, Σ-Δ ADC and an on-chip oscillator. Consuming only 135 µA, the AD7171 is particularly suitable for portable or battery operated products where very low power is a requirement. The AD7171 also has a power-down mode in which the device consumes 5μA, thus increasing the battery life of the product. For ease of use, dedicated pins control all of the features of the AD7171. Each time a data read occurs, eight status bits are appended to the 16bit conversion. These status bits contain a pattern sequence that can be used to confirm the validity of the serial transfer. The output data rate of the AD7171 is 125 Hz, whereas the settling time is 24ms. Typical application includes weigh scales, pressure measurement, industrial process control and portable instrumentation.
