The AD7171BCPZ-500RL7 is a very low power, 16-bit, sigma-delta analog-to-digital converter (ADC) from Analog Devices. It contains a precision 16-bit Σ-Δ ADC and an on-chip oscillator, consuming only 135 µA typical supply current, making it suitable for portable or battery-operated products. A power-down mode reduces current to 5 µA.
The ADC offers a single differential input with an external reference, SPI-compatible 2-wire serial interface, and a programmable output data rate of 125 Hz. The device achieves 16-bit effective number of bits (ENOB) with a settling time of 24 ms. RMS noise is 11.5 µV at VREF=5V and 6.9 µV at VREF=3V.
The AD7171BCPZ-500RL7 operates from a supply voltage range of 2.7V to 5.25V and over a temperature range of -40°C to +105°C. It is housed in a 10-lead 3 mm × 3 mm LFCSP (lead-frame chip-scale package) with exposed pad for surface mount assembly. Typical applications include weigh scales, pressure measurement, industrial process control, and portable instrumentation.
The supply voltage range is 2.7V to 5.25V.
It is available in a 10-VFDFN Exposed Pad, CSP (10-LFCSP-WD 3x3mm) package.
The operating temperature range is -40°C to +105°C.
It is listed as RoHS3 compliant, but this is unverified and has low confidence.
The output data rate is 125 Hz.
Typical supply current is 135 µA in active mode and 5 µA in power-down mode.
It uses a SPI-compatible 2-wire serial interface.
