Description and Introduction

2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs The MAX518ACSA is a dual, 8-bit, voltage-output digital-to-analog converter (DAC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 8-bit  
- **Number of Channels:** 2 (Dual)  
- **Interface Type:** I²C-Compatible Serial Interface  
- **Supply Voltage:** +5V  
- **Output Type:** Voltage  
- **Settling Time:** 6µs (Typical)  
- **DNL (Differential Nonlinearity):** ±1 LSB (Max)  
- **INL (Integral Nonlinearity):** ±1 LSB (Max)  
- **Power Consumption:** 1.5mA (Typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin SOIC  

### **Descriptions and Features:**  
- **Dual DACs in a Single Package:** Contains two independent 8-bit DACs.  
- **I²C-Compatible Serial Interface:** Supports standard two-wire serial communication.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Rail-to-Rail Output Buffer Amplifiers:** Provides a wide dynamic output range.  
- **Internal Precision Bandgap Reference:** Ensures stable output voltage.  
- **Power-On Reset Circuit:** Initializes DAC outputs to zero at startup.  
- **Space-Saving SOIC Package:** Compact 8-pin design for PCB efficiency.  

The MAX518ACSA is commonly used in industrial control systems, digital gain and offset adjustment, and programmable voltage sources.

Application Scenarios & Design Considerations

2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs

Alternative Part Number

  • AD5340BRZ --: Dual 8-bit voltage-output DAC with I2C-compatible interface, functionally similar to the MAX518 and available from a different manufacturer and series.
  • MCP4822-E/P --: Dual 12-bit DAC with SPI interface offering higher resolution than the original 8-bit part, suitable as an upgrade in many designs.
  • LTC1661CMS8 --: Dual 10-bit DAC in a small package with serial interface, a practical alternative when the MAX518 is unavailable.
  • AD5300BRMZ --: Single-channel 8-bit voltage-output DAC with similar serial interface and supply range; Analog Devices is the direct successor brand for Maxim parts and offers comparable performance.
  • LTC1655CS8 --: 8-bit rail-to-rail voltage-output DAC in a small package with serial interface, functionally similar to the MAX518 and readily available.
