The AD7171 is a very low power 16-bit analog-to-digital converter (ADC). It contains a precision 16-bit sigma-delta (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 5 μA, thus increasing the battery life of the product.
