Description and Introduction

Octal 16-/12-Bit Rail-to-Rail DACs with 10ppm/掳C Max Reference The LTC2656CUFD-L12#PBF is a 12-bit digital-to-analog converter (DAC) manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Number of Channels:** 4  
- **Interface Type:** I²C (2-wire serial)  
- **Supply Voltage:** 2.7V to 5.5V  
- **Output Type:** Voltage (buffered)  
- **Output Range:** 0V to VREF or 0V to 2 × VREF (selectable)  
- **Reference Voltage:** Internal (10ppm/°C max drift) or External (up to 5.5V)  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±4 LSB (max)  
- **Settling Time:** 4.5µs (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead QFN (4mm × 4mm)  

### **Descriptions:**  
The LTC2656CUFD-L12#PBF is a quad 12-bit DAC with an integrated precision reference. It provides rail-to-rail output buffering and supports both internal and external reference modes. The I²C interface allows for easy communication with microcontrollers and other digital systems.  

### **Features:**  
- **Four Independent DAC Channels**  
- **Integrated 10ppm/°C Max Reference (1.25V or 2.5V selectable)**  
- **Guaranteed Monotonicity**  
- **Low Power Operation (0.5mA per DAC at 3V)**  
- **Power-On Reset to Zero-Scale or Mid-Scale**  
- **Software and Hardware Power-Down Modes**  
- **Small 16-Lead QFN Package**  

This DAC is suitable for industrial control, instrumentation, and communication systems requiring high precision and low power consumption.
