Description and Introduction

CMOS, 12-Bit, Seral-Input Multiplying DAC The MAX543ACPA is a precision 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)  
- **Model:** MAX543ACPA  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  
- **Resolution:** 12-bit  
- **Interface:** Serial (SPI/QSPI/MICROWIRE compatible)  
- **Supply Voltage:** +5V (single supply)  
- **Output Type:** Voltage output  
- **Output Range:** 0V to VREF (programmable)  
- **Reference Input:** External (requires an external reference voltage)  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±1 LSB (max)  
- **Settling Time:** 10µs (typical)  
- **Power Consumption:** 1.5mW (typical)  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)  

### **Descriptions:**  
The MAX543ACPA is a 12-bit serial-input, voltage-output digital-to-analog converter (DAC) designed for precision applications. It features a simple 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The device requires an external reference voltage to set the output range and provides a buffered voltage output.  

### **Features:**  
- **12-bit resolution** for precise analog output control  
- **Low power consumption** (1.5mW typical)  
- **Single +5V supply operation**  
- **SPI/QSPI/MICROWIRE-compatible serial interface**  
- **Buffered voltage output** for direct drive capability  
- **External reference input** for flexible output scaling  
- **±1 LSB INL and DNL** for high accuracy  
- **Fast settling time (10µs typical)**  
- **8-pin PDIP package** for easy prototyping  

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