Description and Introduction

Complete SO-8/ 12-Bit/ 200ksps ADC with Shutdown The LTC1401CS8 is a high-speed, 14-bit analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 14 bits  
- **Sampling Rate:** 1.25 MSPS (Million Samples Per Second)  
- **Input Type:** Single-ended  
- **Input Voltage Range:** 0V to 2.5V (unipolar) or ±1.25V (bipolar)  
- **Power Supply:** Single +5V  
- **Power Consumption:** 85mW (typical)  
- **DNL (Differential Non-Linearity):** ±0.5 LSB (max)  
- **INL (Integral Non-Linearity):** ±1.5 LSB (max)  
- **SNR (Signal-to-Noise Ratio):** 80dB (typical)  
- **THD (Total Harmonic Distortion):** -90dB (typical)  
- **Package:** 8-Lead SOIC  

### **Descriptions and Features:**  
- **High-Speed Performance:** 1.25MSPS throughput with no pipeline delay.  
- **Low Power:** Consumes only 85mW at full speed.  
- **Internal Reference:** Includes a 2.5V precision reference.  
- **No Missing Codes:** Guaranteed over the full temperature range.  
- **Flexible Input Range:** Supports both unipolar (0V to 2.5V) and bipolar (±1.25V) operation.  
- **Serial Interface:** SPI-compatible for easy interfacing with microcontrollers and DSPs.  
- **Wide Temperature Range:** Operates from -40°C to +85°C.  

This ADC is suitable for high-speed data acquisition, medical imaging, communications, and industrial applications.  

(Note: Specifications are based on the manufacturer's datasheet.)

Application Scenarios & Design Considerations

Alternative Part Number

  • ADC081S021CIMM --: 8-bit 200ksps serial ADC in small package, functionally similar to the LTC1401 and widely available as a lower-cost alternative.
  • MCP3201-BI/P --: 12-bit single-channel SPI ADC with comparable resolution and simple serial interface, suitable replacement for low-speed sampling applications.
  • ADS7816U --: 12-bit 200ksps serial ADC in SOIC package, pin-function compatible for many LTC1401 designs with similar supply and interface.
  • ADC0831CCN --: 8-bit serial ADC in 8-pin package, functionally similar to the LTC1401 for low-speed single-channel sampling applications.
  • MCP3201-CI/P --: 12-bit SPI ADC in 8-pin package offering comparable resolution and simple serial interface, suitable as a drop-in functional substitute.
  • ADS7816P --: 12-bit serial ADC in 8-pin DIP with similar sampling architecture and interface, a practical alternative when the original is unavailable.
