Description and Introduction

Single 12-/10-/8-Bit SPI VOUT DACs with 10ppm/掳C Reference The LTC2640CTS8-HZ8#PBF 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:** 1  
- **Interface Type:** SPI  
- **Supply Voltage:** 2.7V to 5.5V  
- **Output Type:** Voltage (Buffered)  
- **Output Range:** 0V to VREF  
- **Reference Voltage:** Internal (2.048V) or External (up to VDD)  
- **DNL (Differential Non-Linearity):** ±1 LSB (max)  
- **INL (Integral Non-Linearity):** ±1 LSB (max)  
- **Settling Time:** 4.5µs (typ)  
- **Power Consumption:** 0.7mA (typ) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSOT-8  

### **Descriptions:**  
The LTC2640 is a precision 12-bit DAC with an internal reference and SPI interface. It provides a buffered voltage output with low noise and high accuracy. The device operates from a single supply and includes a power-on reset circuit that ensures the DAC output initializes to zero scale.  

### **Features:**  
- **Internal 2.048V Reference** (10ppm/°C drift)  
- **SPI-Compatible Serial Interface** (up to 50MHz)  
- **Guaranteed Monotonic** over temperature  
- **Low Glitch Impulse:** 0.1nV-s  
- **Power-On Reset to Zero Scale**  
- **Rail-to-Rail Output Buffer**  
- **Small TSOT-8 Package**  

This DAC is suitable for industrial control, instrumentation, and other precision analog applications.
