**AD7321BRUZ-REEL: A Versatile 12-Bit ADC for Complex Analog Systems**

In the realm of data acquisition, the ability to accurately digitize a wide range of analog signals directly from sensors is paramount. The **AD7321BRUZ-REEL** from Analog Devices stands out as a highly integrated solution designed to tackle this very challenge. This 12-bit, successive approximation register (SAR) analog-to-digital converter (ADC) combines high performance with exceptional flexibility, making it an ideal choice for industrial instrumentation, automated test equipment, and complex control systems.

The core of the AD7321's appeal lies in its **software-configurable true bipolar input ranges**. Unlike many ADCs that require external signal conditioning circuitry to handle bipolar signals (those with both positive and negative voltages), the AD7321 integrates this capability on-chip. Through a simple serial interface write, each of its eight input channels can be individually configured to accept one of four input ranges: ±10V, ±5V, ±2.5V, or 0 to +10V. This eliminates the need for external level-shifting and scaling components, **significantly simplifying board design**, reducing overall system cost, and enhancing reliability.

Beyond its versatile input handling, the AD7321 delivers robust performance. It features a high throughput rate of up to **1 MSPS**, allowing for the rapid sampling of dynamic signals across all channels. An integrated sequencer further optimizes multi-channel operation by allowing a pre-programmed selection of channels to be converted in sequence, reducing the software overhead on the host processor. The device is built on a proprietary SAR architecture that ensures no missing codes at 12 bits and provides excellent **AC and DC performance specifications**.

Housed in a compact 20-lead TSSOP package, the AD7321BRUZ-REEL is supplied in a reel format suitable for high-volume automated manufacturing. It operates from a single 2.7 V to 5.25 V supply, while the analog inputs can handle the much higher bipolar voltages, thanks to its internal architecture.

**ICGOOODFIND**: The AD7321BRUZ-REEL is a powerhouse of integration and flexibility. Its software-configurable bipolar inputs are a standout feature, offering unprecedented design simplicity for systems that must interface with diverse analog sensors. It is a superior choice for engineers seeking to reduce component count while maintaining high accuracy and performance in multi-channel data acquisition systems.
