Description and Introduction

Dual, 12-Bit, Low-Power, 2-Wire, Serial Voltage-Output DAC The MAX5822LEUA+ 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  
- **Part Number:** MAX5822LEUA+  
- **Type:** 12-bit, dual-channel, voltage-output DAC  
- **Interface:** I²C-compatible (2-wire serial)  
- **Supply Voltage:** +2.7V to +5.5V  
- **Output Voltage Range:** 0V to VDD  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±1 LSB (max)  
- **Settling Time:** 6µs (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (MSOP)  

### **Descriptions:**  
The MAX5822LEUA+ is a low-power, dual-channel, 12-bit DAC with an I²C-compatible interface. It provides rail-to-rail voltage outputs and includes a power-on reset circuit that ensures the DAC outputs initialize to zero. It is designed for precision analog applications requiring minimal power consumption.  

### **Features:**  
- Dual 12-bit DACs in a single package  
- Low power consumption: 0.4mA (typ) at 3V  
- Internal precision output amplifier (rail-to-rail)  
- Power-on reset to zero-scale/midscale (software selectable)  
- Three software-selectable power-down modes  
- Small 8-pin µMAX package  

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

Application Scenarios & Design Considerations

Dual, 12-Bit, Low-Power, 2-Wire, Serial Voltage-Output DAC

Alternative Part Number

  • MCP4725A0T-E/CH --: Single-channel 12-bit I2C DAC in SOT-23-6, functionally similar to the MAX5822 and widely available as a direct alternative.
  • DAC7571IDBVR --: 12-bit I2C DAC in SOT-23-6 with comparable resolution and interface, suitable drop-in replacement in most designs.
  • AD5621BRTZ-500RL7 --: 12-bit DAC in SOT-23 package with similar serial interface and performance, good alternative when higher accuracy is needed.
  • AD5662BRMZ-1 --: Pin-compatible 12-bit DAC with similar I2C interface and small package, widely available from a different vendor.
