Description and Introduction

Quad 16-/14-/12-Bit Rail-to-Rail DACs with I2C Interface The LTC2629CGN-1 is a 12-bit voltage-output DAC (Digital-to-Analog Converter) manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 12 bits  
- **Number of Channels:** 4  
- **Output Type:** Voltage  
- **Interface Type:** SPI  
- **Supply Voltage:** 2.7V to 5.5V  
- **Reference:** Internal or External  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±4 LSB (max)  
- **Settling Time:** 4.5µs (typical)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Lead SSOP  

### **Descriptions and Features:**  
- **Quad DAC:** Four independent 12-bit DACs in a single package.  
- **Low Power:** Operates with a single supply (2.7V to 5.5V).  
- **Internal Reference:** Includes a 2.5V reference (10ppm/°C typical drift).  
- **SPI Interface:** Supports 50MHz SPI-compatible serial interface.  
- **Rail-to-Rail Output:** Buffered voltage output swings from 0V to VREF.  
- **Power-On Reset:** Outputs reset to zero-scale or mid-scale (user-selectable).  
- **Low Glitch Impulse:** Minimizes output transients during updates.  
- **Applications:** Industrial control, instrumentation, automated test equipment, and process control.  

The LTC2629CGN-1 is designed for precision applications requiring multiple DAC channels with low power consumption and high accuracy.
