AD7701ARZ-REEL

The AD7701ARZ-REEL from Analog Devices is a high-performance, 16-bit Analog-to-Digital Converter (ADC) based on sigma-delta conversion techniques. This monolithic IC features on-chip self-calibration circuitry to ensure endpoint accuracy and null system offset and gain errors. It offers a programmable low-pass filter with a corner frequency range of 0.1 Hz to 10 Hz and supports analog input ranges of 0 V to +2.5 V or -2.5 V.

With an output data rate of up to 4 kSPS, the AD7701ARZ-REEL is suitable for applications requiring precise measurement. Its flexible serial interface is compatible with UARTs and microcontrollers. The device boasts ultralow power consumption, making it ideal for portable instrumentation and remote data acquisition systems.

This ADC is housed in a 20-SOIC package and designed for surface mount applications. Its operating temperature range is -40°C to 85°C. Key features include 16-bit resolution, 0.0015% linearity error, and on-chip calibration, making it a robust choice for industrial process control and weigh scales.

The AD7701ARZ-REEL integrates an analog modulator, a 6-pole Gaussian digital filter, and a serial interface logic. The master clock input can be supplied externally or by an on-chip clock oscillator. The device also includes a power-down mode that reduces idle power consumption to just 10 µW.
