Description and Introduction

Complete SO-8/ 12-Bit/ 200ksps ADC with Shutdown The LTC1401IS8 is a high-performance, 14-bit analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 14-bit  
- **Sampling Rate:** 1.25 MSPS (Million Samples Per Second)  
- **Input Voltage Range:** ±2.5V (Differential)  
- **Power Supply:** Single +5V  
- **Power Consumption:** 75mW (Typical)  
- **DNL (Differential Non-Linearity):** ±0.5 LSB (Max)  
- **INL (Integral Non-Linearity):** ±1 LSB (Max)  
- **SNR (Signal-to-Noise Ratio):** 82dB (Typical)  
- **THD (Total Harmonic Distortion):** -90dB (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**
- The LTC1401IS8 is a high-speed, low-power, 14-bit ADC designed for precision data acquisition applications.  
- It features a differential input, providing excellent noise immunity and high accuracy.  
- The device includes a high-speed serial interface for easy integration with microcontrollers and DSPs.  
- It is well-suited for industrial, medical, and communications applications requiring high-resolution conversion.  

### **Features:**
- **High-Speed 14-Bit ADC:** Delivers 1.25 MSPS throughput.  
- **Low Power:** Consumes only 75mW at full speed.  
- **Differential Input:** Supports ±2.5V range for noise rejection.  
- **Serial Interface:** SPI-compatible for easy interfacing.  
- **Internal Reference:** Includes a 2.5V reference for simplified design.  
- **No Pipeline Delay:** Provides accurate real-time conversion.  
- **Wide Temperature Range:** Operates from -40°C to +85°C.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Alternative Part Number

  • ADC121S021CIMM --: 12-bit 200kSPS SAR ADC in 8-pin MSOP, similar function and resolution to the LTC1401, widely available and pin-compatible in function.
  • MCP3201-BI/SN --: 12-bit 100kSPS SPI ADC in 8-pin SOIC, same package and serial interface, good drop-in functional alternative for low-speed sampling.
  • ADS7816U --: 12-bit 200kSPS micropower ADC in 8-pin SOIC with SPI interface, comparable performance and package to the LTC1401IS8.
  • AD7819YRZ --: Similar 8-bit SAR ADC with serial interface in SOIC-8, pin-compatible family from the same analog vendor lineage.
  • MAX1112CPE --: Comparable low-power 8-bit serial ADC offering similar sampling rate and supply range for drop-in evaluation.
  • TLC549ID --: Widely available 8-bit successive-approximation ADC with serial output, suitable functional substitute in SOIC package.
