Description and Introduction

Quad/Octal, 2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs The MAX521ACAG is a precision, low-power, 8-bit digital-to-analog converter (DAC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- Maxim Integrated (now Analog Devices)  

### **Key Specifications:**  
- **Resolution:** 8-bit  
- **Number of Channels:** 1 (single-channel DAC)  
- **Interface Type:** Serial (SPI/QSPI/MICROWIRE compatible)  
- **Supply Voltage:** +5V (single supply)  
- **Output Type:** Voltage output (buffered)  
- **Settling Time:** 10µs (typical)  
- **DNL (Differential Non-Linearity):** ±0.5 LSB (max)  
- **INL (Integral Non-Linearity):** ±1 LSB (max)  
- **Power Consumption:** 1.4mW (typical)  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)  
- **Package:** 24-pin SSOP (Shrink Small Outline Package)  

### **Descriptions & Features:**  
- **Precision DAC:** Provides accurate 8-bit voltage output with low integral and differential non-linearity.  
- **Low Power Consumption:** Designed for power-sensitive applications.  
- **Serial Interface:** Compatible with SPI, QSPI, and MICROWIRE for easy microcontroller interfacing.  
- **Internal Reference:** Includes an internal precision reference for simplified design.  
- **Buffered Output:** Voltage output is buffered for improved stability and drive capability.  
- **Single-Supply Operation:** Operates from a single +5V supply.  
- **Applications:** Used in industrial control, process automation, digital gain/offset adjustment, and programmable voltage sources.

Application Scenarios & Design Considerations

Quad/Octal, 2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs

Alternative Part Number

  • AD5308ARUZ --: Octal 8-bit voltage-output DAC with similar SPI interface and performance, direct functional replacement in many designs.
  • MCP4922-E/P --: Dual 12-bit DAC with SPI interface, higher resolution and widely available, suitable substitute when channel count is not critical.
  • LTC1660CN8 --: Octal 10-bit DAC with serial interface, comparable resolution and channel count, good alternative for similar applications.
  • AD7243ANZ --: Octal 8-bit voltage-output DAC with similar serial interface and performance, widely available as a MAX521 functional alternative.
  • TLC5620CN --: Quad 8-bit voltage-output DAC with serial control; usable substitute when fewer channels are acceptable and pin-compatible design is not mandatory.
