Description and Introduction

14-Bit Dual Rail-to-Rail DAC with I2C Interface The LTC2617CDE is a dual 16-bit I²C voltage output DAC (Digital-to-Analog Converter) manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 16-bit  
- **Number of Channels:** 2 (Dual)  
- **Interface:** I²C (2-wire serial interface)  
- **Supply Voltage:** 2.7V to 5.5V  
- **Output Voltage Range:** 0V to VREF (external reference dependent)  
- **Reference Input:** External reference required  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±4 LSB (max)  
- **Settling Time:** 8.5μs (typical)  
- **Operating Temperature Range:** 0°C to 70°C (Commercial)  
- **Package:** 14-Lead DFN (4mm × 3mm)  

### **Descriptions and Features:**  
- **High Accuracy:** 16-bit resolution with low DNL and INL errors.  
- **I²C Interface:** Supports standard (100kHz) and fast (400kHz) modes.  
- **Rail-to-Rail Output:** Buffered voltage output swings close to ground and VREF.  
- **Low Power:** Typically consumes 0.7mA at 5V.  
- **Power-On Reset:** Outputs reset to zero-scale or mid-scale (user-selectable).  
- **Small Form Factor:** Compact 14-lead DFN package for space-constrained applications.  
- **Applications:** Industrial control, instrumentation, automated test equipment, and programmable voltage sources.

Application Scenarios & Design Considerations

14-Bit Dual Rail-to-Rail DAC with I2C Interface

Alternative Part Number

  • MCP4728A0-E/UN --: Quad 12-bit I2C DAC in a small package, functionally similar to the LTC2617 and widely available.
  • AD5627BRMZ --: Dual 12-bit I2C DAC with comparable resolution and interface, suitable as a direct functional substitute.
  • DAC7578IPW --: Octal 12-bit I2C DAC offering similar performance and easy drop-in evaluation for DAC designs.
  • AD5662BRMZ-1 --: Single-channel 16-bit DAC with similar I2C interface and small package, pin-compatible in many designs and widely available.
  • DAC7571IDBVR --: 12-bit I2C DAC in SOT-23, low power and cost-effective alternative when 16-bit precision is not strictly required.
