Description and Introduction

12-Bit/ 500ksps Sampling A/D Converter with Shutdown The LTC1278-4CSW is a 12-bit, 250ksps sampling analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 12 bits  
- **Sampling Rate:** 250ksps (kilo samples per second)  
- **Input Voltage Range:** 0V to VREF (external reference)  
- **Power Supply:** Single +5V  
- **Power Consumption:** 75mW (typical)  
- **DNL (Differential Nonlinearity):** ±0.5LSB (max)  
- **INL (Integral Nonlinearity):** ±1LSB (max)  
- **Package:** 24-Lead SOIC (SW)  

### **Descriptions and Features:**  
- **High-Speed ADC:** Capable of 250,000 conversions per second.  
- **Low Power:** Consumes only 75mW at full speed.  
- **Internal Track-and-Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Parallel Output:** 12-bit parallel data output for easy interfacing.  
- **Single +5V Supply Operation:** Simplifies power requirements.  
- **External Reference:** Allows flexibility in setting the input range.  
- **Wide Input Bandwidth:** Suitable for high-frequency signal acquisition.  

This ADC is designed for applications requiring high-speed, low-power, and precision analog-to-digital conversion, such as data acquisition systems, instrumentation, and digital signal processing.

Application Scenarios & Design Considerations

12-Bit/ 500ksps Sampling A/D Converter with Shutdown

Alternative Part Number

  • AD7874ANZ --: 12-bit successive-approximation ADC with similar sampling rate and parallel interface, pin-compatible in many designs and widely available.
  • MAX196BCWI --: 12-bit ADC with comparable speed and parallel output, suitable drop-in replacement for many LTC1278 applications.
  • ADS7804U --: 12-bit SAR ADC with similar performance and interface, good alternative when LTC1278 is unavailable.
