Description

The AD7171 is a very low power, 16-bit, analog-to-digitalconverter (ADC). It contains a precision, 16-bit, ?-? ADC andan on-chip oscillator. Consuming only 135 ?A, the AD7171 isparticularly suitable for portable or battery operated productswhere very low power is a requirement. The AD7171 also has apower-down mode in which the device consumes 5 ?A, thusincreasing the battery life of the product.For ease of use, dedicated pins control all of the features of theAD7171. Each time a data read occurs, eight status bits areappended to the 16-bit conversion. These status bits contain apattern sequence that can be used to confirm the validity of theserial transfer.The output data rate of the AD7171 is 125 Hz, whereas the settlingtime is 24 ms. The AD7171 has one differential input and a gainof 1. This is useful in applications where the user needs to use anexternal amplifier to implement system-specific filtering or gainrequirements.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 samefeature set as the AD7171 and is pin-for-pin compatible.Applications Weigh scales Pressure measurement Industrial process control Portable instrumentation
