GENERAL DESCRIPTION
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 A, 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, all the features of the AD7171 are controlled by
dedicated pins. 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 package.
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.
