AD7715ARZ-3

AD7715ARZ-3 is Analog Devices’ AD7715 precision delta-sigma ADC in a RoHS-compliant package. It converts analog sensor signals to digital with high resolution and low noise, using a serial SPI-like interface. Typical features include differential inputs, programmable data rate, and support for bipolar or unipolar ranges—suitable for instrumentation, weigh scales, and industrial sensors. The -3 suffix indicates a specific packaging variant/temperature grade; check the datasheet for exact pinout and electrical spec. In short, it’s a compact, high-accuracy ADC designed for demanding sensing applications where stability and low power matter.

Direct pin-for-pin equivalents for AD7715ARZ-3 do not exist outside Analog Devices. Closest substitutes are other 24-bit sigma-delta ADCs in the AD771x family (AD7710, AD7711, AD7713, AD7714, AD7716, AD7717, AD7719). If using a different vendor, consider TI ADS1220 or ADS124S08 with similar performance, but verify pinout and interface. For a definitive cross-reference, use ADI’s cross-reference tool or contact sales.

Here are the typical features of the AD7715ARZ-3 (as per the datasheet for this delta-sigma ADC):
- 16-bit resolution, sigma-delta ADC with a programmable digital filter
- SPI-compatible serial interface for easy MCU connection
- External reference input option
- Differential input with selectable gain options
- Programmable data rate and filter settings (tradeoff between speed and noise)
- Low power operation with standby/low-power modes
- Single-supply operation (2.7 V to 5.25 V)
- Industrial/wide operating temperature range suitable for harsh environments
- compact ARZ package (surface-mount, suitable for small-form designs)
Note: For exact timing, pinout, supply ranges, and calibration features, please refer to the official ADI datasheet for AD7715ARZ-3.
