**Uncompromising Precision and Performance**

At the heart of the AD7173-8's capability is its **32-bit sigma-delta architecture**, which is engineered to deliver both high resolution and exceptional accuracy. It achieves a remarkable **±0.5 ppm of INL (Integral Non-Linearity)** and features an ultra-low noise floor, enabling the faithful digitization of even the most minuscule sensor signals. With a maximum throughput of **125 kSPS** in fast settling modes, it adeptly handles both DC and dynamic signal measurements. Furthermore, its integrated **programmable digital filters** provide flexibility, allowing designers to optimize the trade-off between noise rejection and settling time for their specific use case.

**Integrated Features for Simplified Design**

A key advantage of the AD7173-8 is its high level of integration, which significantly reduces the bill of materials and design complexity. The ADC incorporates a **precision, low-noise analog front-end (AFE)** including a programmable gain amplifier (PGA), which allows it to interface directly with a wide variety of sensors, including strain gauges, RTDs, and thermocouples, without requiring extensive external signal conditioning. The device also includes critical diagnostic functions such as **open-circuit, short-circuit, and power supply monitoring**, enhancing system reliability and enabling predictive maintenance capabilities.

**Robust Operation in Demanding Environments**

Designed for harsh industrial environments, the AD7173-8BCPZ-RL offers outstanding robustness. It supports a wide analog input range and operates from a single analog supply from 2.7 V to 3.6 V or a dual ±2.5 V supply. Its **SPI-compatible digital interface** ensures easy connection to a host microcontroller or processor. The device is specified over an extended temperature range (-40°C to +105°C) and is available in a compact **32-lead LFCSP package**, making it suitable for space-constrained, high-reliability applications.
