Description and Introduction

12-Bit, 10mW, 100ksps ADCs with 1碌A Shutdown The LTC1277ISW is a 12-bit, 500ksps sampling analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 12-bit  
- **Sampling Rate:** 500ksps (kilo samples per second)  
- **Input Voltage Range:** 0V to VREF (typically 2.5V or 5V)  
- **Power Supply:** Single +5V  
- **Power Consumption:** 75mW (typical)  
- **DNL (Differential Non-Linearity):** ±0.5 LSB (max)  
- **INL (Integral Non-Linearity):** ±1 LSB (max)  
- **Signal-to-Noise Ratio (SNR):** 72dB (typical)  
- **THD (Total Harmonic Distortion):** -80dB (typical)  
- **Package:** 28-Lead SOIC (SW)  

### **Descriptions and Features:**  
- **High-Speed ADC:** Supports fast conversion with a 500ksps throughput.  
- **Low Power:** Operates at 75mW, making it suitable for power-sensitive applications.  
- **Internal Reference:** Includes a 2.5V reference, but can also accept an external reference.  
- **Parallel Interface:** Provides a 12-bit parallel output for easy interfacing with microcontrollers or DSPs.  
- **Wide Input Bandwidth:** The SHA (Sample-and-Hold) allows accurate capture of high-frequency signals.  
- **Single-Supply Operation:** Simplifies power requirements with a single +5V supply.  
- **Pin-Compatible:** Drop-in compatible with the LTC1278 (12-bit, 600ksps) and LTC1279 (12-bit, 800ksps).  

This ADC is commonly used in data acquisition systems, medical instruments, and industrial control applications.
