**AD5674BCPZ-1: A 16-Bit, Quad-Channel NanoDAC+ with 5 ppm/°C On-Chip Reference**

The **AD5674BCPZ-1** represents a significant advancement in digital-to-analog converter (DAC) technology, integrating high precision, miniaturization, and exceptional stability into a single, compact solution. As a member of Analog Devices' renowned **NanoDAC+** family, this device is engineered for applications where board space, performance, and reliability are paramount.

This converter is a **16-bit, quad-channel voltage-output DAC** that provides four independent output channels, making it an ideal choice for multi-zone control systems, optical networking, industrial automation, and programmable logic controllers (PLCs). Each channel is capable of delivering a well-regulated voltage output, ensuring precise analog control from a digital signal.

A defining feature of the AD5674BCPZ-1 is its **integrated, high-stability on-chip 2.5 V reference**. The reference boasts an ultra-low temperature drift of just **5 ppm/°C**, which is critical for maintaining accuracy over a wide operating temperature range. This eliminates the need for an external reference chip, saving valuable PCB space and reducing both system complexity and bill-of-materials (BOM) costs. The internal gain select amplifier allows for three programmable output ranges: 0 V to VREF, 0 V to 2 × VREF, and the standard ±VREF for bipolar operation, offering exceptional design flexibility.

The device communicates via a versatile **serial peripheral interface (SPI)** that operates at clock rates up to 50 MHz, ensuring fast and efficient data transfer. It also incorporates a **power-on reset circuit** and a **per-channel power-down mode**, which enhances system safety and helps minimize power consumption in energy-sensitive applications. Housed in a small 4 mm × 4 mm **LFCSP (Lead Frame Chip Scale Package)**, the AD5674BCPZ-1 is the perfect blend of high density and high performance.

**ICGOODFIND:** The AD5674BCPZ-1 stands out as a premier solution for designers seeking to maximize performance in space-constrained environments. Its combination of **16-bit resolution, four independent channels, and a highly stable internal reference** makes it a superior choice for creating compact, reliable, and high-accuracy analog output systems.
