Description and Introduction

Dual, 8-Bit, Low-Power, 2-Wire, Serial Voltage-Output DAC The MAX5820LEUA is a 12-bit, octal, voltage-output digital-to-analog converter (DAC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Number of Channels:** 8 (Octal)  
- **Output Type:** Voltage  
- **Interface Type:** Serial (SPI/QSPI/MICROWIRE)  
- **Supply Voltage:** +2.7V to +5.5V  
- **Reference Voltage:** Internal (2.048V) or External (1.25V to VDD)  
- **Output Voltage Range:** 0V to VREF (unbuffered) or 0V to 2×VREF (buffered)  
- **DNL (Differential Non-Linearity):** ±1 LSB (max)  
- **INL (Integral Non-Linearity):** ±1 LSB (max)  
- **Settling Time:** 10µs (typical)  
- **Power Consumption:** 4mW (typical at 3V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX  

### **Descriptions:**  
The MAX5820LEUA is a low-power, octal, 12-bit DAC with an internal precision reference. It provides eight voltage outputs with flexible output ranges and includes a power-on reset circuit that ensures the DAC outputs initialize to zero.  

### **Features:**  
- **8 Independent DAC Channels**  
- **Internal 2.048V Reference**  
- **SPI/QSPI/MICROWIRE-Compatible Serial Interface**  
- **Rail-to-Rail Output Buffer Amplifiers**  
- **Low Power Consumption**  
- **Power-On Reset to Zero-Scale**  
- **Software and Hardware Shutdown Modes**  
- **Small 8-Pin µMAX Package**  

The device is suitable for industrial control, automated test equipment, and digital gain/offset adjustment applications.
