Description and Introduction

12-Bit Rail-to-Rail DACs in 10-Lead DFN The LTC2621CDD-1#TRPBF is a 12-bit voltage output DAC (Digital-to-Analog Converter) manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Number of Channels:** 1  
- **Interface Type:** SPI  
- **Supply Voltage:** 2.7V to 5.5V  
- **Output Type:** Voltage  
- **Output Range:** 0V to VREF  
- **Reference Voltage:** Internal or External (up to VDD)  
- **DNL (Differential Non-Linearity):** ±1 LSB (max)  
- **INL (Integral Non-Linearity):** ±1 LSB (max)  
- **Settling Time:** 4.5µs (typical)  
- **Power Consumption:** 0.7mW (typical at 5V)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  

### **Descriptions & Features:**  
- **Single-Channel DAC:** Provides a single voltage output.  
- **Low Power Operation:** Suitable for battery-powered applications.  
- **Internal Reference:** Optional 2.048V reference (LTC2621-1 variant).  
- **SPI-Compatible Interface:** Supports 50MHz clock rate.  
- **Rail-to-Rail Output Buffer:** Ensures full-scale output swing.  
- **Power-On Reset:** Output resets to zero-scale or mid-scale (programmable).  
- **Small Form Factor:** 10-lead DFN package for space-constrained designs.  

This DAC is commonly used in industrial control, instrumentation, and portable devices requiring precise analog voltage generation.

Application Scenarios & Design Considerations

12-Bit Rail-to-Rail DACs in 10-Lead DFN

Alternative Part Number

  • MCP4725A0T-E/CH --: Single-channel 12-bit DAC with I2C interface in a small SOT-23-6 package, functionally similar to the LTC2621 and widely available.
  • DAC7571IDBVR --: 12-bit single-channel I2C DAC in SOT-23-6, comparable resolution and interface, suitable drop-in functional replacement.
  • AD5621BRTZ-500RL7 --: 12-bit single-channel DAC with SPI interface in SOT-23-6, similar performance class and package for design substitution.
