Description and Introduction

Dual, 8-Bit, Voltage-Output Serial DAC in 8-Pin SO Package The MAX522CSA is a digital-to-analog converter (DAC) manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX522CSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Resolution:** 8-bit  
- **Number of Channels:** Dual (2 independent DACs)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Supply Voltage:** +5V single supply  
- **Reference Voltage:** Internal (2.048V) or External (1.25V to VDD)  
- **Output Type:** Voltage output  
- **Settling Time:** 10µs (typical)  
- **Power Consumption:** 1.5mA (typical)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial grade)  

### **Descriptions:**  
The MAX522CSA is a dual, 8-bit, voltage-output digital-to-analog converter (DAC) with an SPI-compatible serial interface. It includes an internal precision reference (2.048V) but can also accept an external reference voltage. The device operates from a single +5V supply and provides two independent DAC outputs.  

### **Features:**  
- **Dual 8-Bit DACs:** Two independent voltage-output DACs in a single package.  
- **SPI/QSPI/MICROWIRE-Compatible Interface:** Easy interfacing with microcontrollers.  
- **Internal 2.048V Reference:** Eliminates the need for an external reference in some applications.  
- **Low Power Consumption:** Typically 1.5mA supply current.  
- **Rail-to-Rail Output Buffer Amplifiers:** Ensures wide dynamic range.  
- **Power-On Reset:** Outputs reset to zero-scale at power-up.  
- **Small Footprint:** 8-pin SOIC package for space-constrained applications.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Dual, 8-Bit, Voltage-Output Serial DAC in 8-Pin SO Package

Alternative Part Number

  • MCP4822-E/P --: Dual 12-bit DAC with SPI interface in 8-pin PDIP, functionally similar to the MAX522 and widely available.
  • AD7303BNZ --: Dual 8-bit voltage-output DAC with serial interface in 8-pin PDIP, close match to MAX522 specifications.
  • LTC1257CN8 --: 12-bit voltage-output DAC in 8-pin PDIP with simple serial interface, suitable replacement for low-resolution DAC applications.
  • AD5300BRMZ --: Single 8-bit voltage-output DAC with SPI interface, functionally similar to the MAX522 dual 8-bit DAC and available in a small MSOP package.
