Description and Introduction

Quad/Octal, 2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs The MAX521AEWG+T is a high-performance, 16-bit digital-to-analog converter (DAC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 16-bit  
- **Number of Channels:** 1  
- **Interface Type:** Serial (SPI/QSPI/MICROWIRE compatible)  
- **Supply Voltage:** +5V (single supply)  
- **Output Type:** Voltage (buffered)  
- **Settling Time:** 10µs (typical)  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±4 LSB (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin SOIC (Wide)  

### **Descriptions and Features:**  
- **High Accuracy:** Provides 16-bit monotonic performance with low noise.  
- **Serial Interface:** Compatible with SPI, QSPI, and MICROWIRE for easy microcontroller interfacing.  
- **Low Power Consumption:** Typically consumes 2.5mA in active mode.  
- **On-Chip Output Buffer:** Ensures low impedance and fast settling time.  
- **Power-On Reset:** Output resets to zero-scale at power-up.  
- **Rail-to-Rail Output:** Supports a wide dynamic range.  
- **Applications:** Industrial automation, process control, test equipment, and precision instrumentation.  

This DAC is designed for applications requiring high resolution and accuracy with minimal external components.
