**AD5662ARJZ-2REEL7: A 16-Bit nanoDAC for Precision Voltage Output Applications**

In the realm of precision analog signal generation, the **AD5662ARJZ-2REEL7** from Analog Devices stands out as a premier solution for applications demanding high accuracy and minimal power consumption. This 16-bit, single-channel, voltage-output digital-to-analog converter (DAC) is engineered to deliver exceptional performance in a compact package, making it an ideal choice for a wide array of industrial, communication, and instrumentation systems.

The core of the AD5662's performance lies in its **16-bit resolution**, which ensures an exceptionally fine output voltage step size. This high resolution is critical for applications requiring precise control and minimal quantization error, such as programmable voltage sources, industrial process control, and automated test equipment. The device operates from a single 2.7 V to 5.5 V supply, drawing a remarkably low current of 0.18 mA at 3 V, categorizing it firmly within the **ultra-low-power nanoDAC® family**. This feature is paramount for **battery-powered and portable devices** where extending operational life is a critical design constraint.

Housed in a space-saving 8-lead SOT-23 package, the AD5662 offers significant board space efficiency without compromising on functionality. It includes a versatile **2-wire serial interface** (I²C-compatible) that supports standard, fast, and high-speed mode, allowing for easy communication with microcontrollers and digital processors while facilitating simple daisy-chaining of multiple devices. The on-chip output buffer amplifier is designed to drive the output to both supply rails, enhancing its versatility in single-supply operations.

A key to its precision is the **integrated precision reference**. The AD5662ARJZ-2REEL7 variant features an internal 2.5 V reference with a very low typical drift of 2 ppm/°C. This eliminates the need for an external reference component, reduces the overall system parts count, saves board space, and ultimately lowers the total system cost while guaranteeing stable and accurate output performance over a wide temperature range (-40°C to +125°C).

**ICGOOODFIND:** The AD5662ARJZ-2REEL7 is a highly integrated, precision 16-bit DAC that masterfully combines **ultra-low power consumption**, a tiny form factor, and a high-accuracy internal reference. It is an outstanding choice for designers seeking to enhance resolution and reliability in space- and power-constrained precision analog output systems.
