16位低功耗Σ-Δ型ADC 16-Bit Low Power Sigma-Delta ADC
Product Details
The AD7171 is a very low power, 16-bit, analog-to-digital converter ADC. It contains a precision, 16-bit, 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.
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 125 Hz, whereas the settling time is 24 ms. 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.
The AD7171 operates with a power supply from 2.7 V to 5.25 V. It is available in a 10-lead LFCSP.
The AD7170 is a 12-bit version of the AD7171. It has the same feature set as the AD7171 and is pin-for-pin compatible.
