AD7171BCPZ-500RL7

The AD7171BCPZ-500RL7 is a very low power 16-bit Analog-to-digital Converter (ADC) contains an on-chip oscillator. Consuming only 135µA, 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 16-bit 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 125Hz whereas the settling time is 24ms. The AD7171 has one differential input and a gain of 1. This is useful in applications where the user needs to use an external amplifier to implement system-specific filtering or gain requirements.
