Description and Introduction

Quad 12-/10-/8-Bit Rail-to-Rail DACs with 10ppm/°C Reference The LTC2634-HMX8 is a family of octal 12-/10-/8-bit voltage-output DACs with an integrated, high-accuracy, low-drift reference. It is manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 12-bit (LTC2634-HMX12), 10-bit (LTC2634-HMX10), or 8-bit (LTC2634-HMX8)  
- **Channels:** 8 independent DACs  
- **Output Range:**  
  - 0V to 2.5V (internal reference)  
  - 0V to 4.096V (internal reference)  
  - ±2.5V (external reference)  
- **Integrated Reference:**  
  - 2.5V or 4.096V selectable  
  - Low drift: 10ppm/°C (typical)  
- **Interface:** I²C-compatible, 2-wire serial  
- **Supply Voltage:** 2.7V to 5.5V  
- **Power Consumption:**  
  - 0.7mA (typical) per DAC at 3.6V  
  - Low-power shutdown mode: <1µA (typical)  
- **Settling Time:** 6µs (typical) to ±1LSB  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead SSOP  

### **Features:**  
- **High Accuracy:** ±1LSB INL and DNL (max)  
- **Rail-to-Rail Output:** Buffered voltage output  
- **Power-On Reset:** DACs reset to zero-scale or midscale (programmable)  
- **Software and Hardware LDAC Control:** Synchronous or independent DAC updates  
- **Address Pins:** Allows multiple devices on the same bus  

The LTC2634-HMX8 is designed for precision industrial, automotive, and instrumentation applications requiring multiple DACs with integrated references.
