Description and Introduction

Serial, CMOS, Multiplying, 12-Bit DAC in 8-Pin Package The MAX543AEPA+ is a precision digital-to-analog converter (DAC) manufactured by **MAXIM** (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Interface Type:** Serial (SPI/QSPI/MICROWIRE compatible)  
- **Supply Voltage Range:** +5V (single supply)  
- **Output Type:** Voltage output  
- **Output Range:** 0V to VREF (external reference dependent)  
- **Reference Input:** External (requires reference voltage)  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±1 LSB (max)  
- **Settling Time:** 10µs (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin PDIP  

### **Descriptions:**  
The MAX543AEPA+ is a **12-bit multiplying DAC** designed for precision applications. It features a **serial interface** for easy microcontroller integration and operates from a **single +5V supply**. The device requires an **external reference voltage** to set the output range.  

### **Features:**  
- **Low Power Consumption:** 0.5mW (typical)  
- **SPI/QSPI/MICROWIRE-Compatible Serial Interface**  
- **Buffered Voltage Output**  
- **Monotonic Over Temperature**  
- **Low Glitch Energy:** 5nV-s (typical)  
- **Power-On Reset Clears DAC Output to Zero**  

This DAC is suitable for applications such as **industrial control systems, automated test equipment, and digital calibration**.

Application Scenarios & Design Considerations

Serial, CMOS, Multiplying, 12-Bit DAC in 8-Pin Package

Alternative Part Number

  • AD5421BRZ --: Pin-compatible 12-bit multiplying DAC in DIP-8 with similar serial interface and reference input, direct functional replacement from the original Maxim/ADI family.
  • DAC8043AEPZ --: 12-bit current-output multiplying DAC in PDIP-8 with comparable accuracy and settling time, suitable drop-in substitute for the MAX543AEPA+.
  • MCP4921-E/P --: 12-bit SPI DAC in PDIP-8 offering similar resolution and serial control, a cost-effective alternative when exact pinout matching is not critical.
