AD7171 Datasheet | Analog Devices

FEATURES Output data rate: 125 Hz Pin-programmable power-down and reset Status function Internal clock oscillator Current: 135 µA Power supply: 2.7 V to 5.25 V - 40°C to +105°C temperature range Package: 10-lead 3 mm × 3 mm LFCSP INTERFACE 2-wire serial (read-only device) SPI patible Schmitt trigger on SCLK APPLICATIONS Weigh scales Pressure measurement Industrial process control Portable instrumentation GENERAL DESCRIPTION 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.
