The AD7721ARZ is a complete low-power, 12-/16-bit sigma-delta analog-to-digital converter (ADC) from Analog Devices. It operates from a single +5V supply and accepts a differential input voltage range of 0V to 2.5V or ±1.25V. The sigma-delta architecture provides excellent linearity and DC accuracy, with on-chip calibration minimizing zero-scale and full-scale errors.
The ADC supports both serial (SPI) and parallel data interfaces, with a maximum sampling rate of 312.5 kHz in parallel mode and 468.75 kHz in serial mode. The input bandwidth extends to 229.2 kHz, and the output word rate reaches 468.75 kHz. The device includes a power-down mode reducing consumption to 100 µW. The AD7721ARZ is housed in a 28-SOIC surface-mount package and operates over the industrial temperature range of -40°C to 85°C.
