Description and Introduction

Micropower Sampling 12-Bit A/D Converters In S0-8 Packages The LTC1298 is a 12-bit data acquisition system (DAS) manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features of the LTC1298:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential inputs  
- **Conversion Time:** 12µs (typical)  
- **Throughput Rate:** 60ksps (max)  
- **Input Voltage Range:** 0V to VREF (single-ended) or ±VREF (differential)  
- **Reference Voltage (VREF):** External, up to supply voltage  
- **Supply Voltage (VCC):** 4.75V to 6V  
- **Power Consumption:** 15mW (typical)  
- **Interface:** SPI/Microwire-compatible serial interface  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 16-pin PDIP, SOIC, and SW packages  

### **Descriptions:**  
The LTC1298 is a low-power, 12-bit successive approximation register (SAR) ADC with an integrated multiplexer. It is designed for precision data acquisition applications requiring high-speed, low-power operation. The device includes an onboard sample-and-hold circuit and communicates via a 3-wire serial interface, making it suitable for microcontroller-based systems.  

### **Features:**  
- **12-Bit Resolution** – Provides accurate analog-to-digital conversion.  
- **Flexible Input Configuration** – Supports 8 single-ended or 4 differential channels.  
- **Low Power Consumption** – Typically 15mW at 5V supply.  
- **Fast Conversion Time** – 12µs per conversion.  
- **SPI/Microwire-Compatible Interface** – Easy integration with microcontrollers.  
- **On-Chip Sample-and-Hold** – Eliminates the need for external circuitry.  
- **Wide Operating Temperature Range** – Suitable for industrial applications.  

For detailed electrical characteristics and application notes, refer to the official LTC1298 datasheet from Analog Devices.
