Description and Introduction

Low Power 14-Bit/ 400ksps Sampling ADC The LTC1416IG 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 bits  
- **Sampling Rate:** Up to 400 kSPS (kilo samples per second)  
- **Input Voltage Range:** ±10V (bipolar) or 0V to +10V (unipolar)  
- **DNL (Differential Non-Linearity):** ±1 LSB (max)  
- **INL (Integral Non-Linearity):** ±2 LSB (max)  
- **Signal-to-Noise Ratio (SNR):** 82 dB (typical)  
- **Total Harmonic Distortion (THD):** -90 dB (typical)  
- **Power Supply:** Single +5V supply  
- **Power Consumption:** 95 mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead SSOP  

### **Descriptions:**
- The LTC1416IG is a high-speed, low-power, 14-bit ADC designed for precision data acquisition applications.  
- It features a successive approximation register (SAR) architecture with a fast conversion time.  
- The device includes an internal high-accuracy reference and a sample-and-hold circuit.  
- It supports both unipolar and bipolar input ranges, making it versatile for various signal conditioning needs.  

### **Features:**
- **High Accuracy:** 14-bit resolution with excellent linearity.  
- **Flexible Input Range:** Supports ±10V (bipolar) and 0V to +10V (unipolar) operation.  
- **Low Power Consumption:** 95 mW typical, suitable for power-sensitive applications.  
- **Internal Reference:** Integrated 2.5V reference with low drift.  
- **Parallel Interface:** Easy interfacing with microprocessors and DSPs.  
- **No Missing Codes:** Guaranteed over the full operating temperature range.  
- **Single Supply Operation:** Simplifies system design.  

The LTC1416IG is commonly used in industrial control, medical instrumentation, and high-precision data acquisition systems.

Application Scenarios & Design Considerations

Low Power 14-Bit/ 400ksps Sampling ADC

Alternative Part Number

  • AD7663ASTZ --: 16-bit successive-approximation ADC with similar speed and parallel interface, pin-compatible family lineage from the same company that acquired Linear Technology.
  • ADS8517IB --: 16-bit SAR ADC offering comparable sampling rate and parallel output, suitable drop-in functional replacement with similar supply requirements.
  • MAX1179BCUI --: 16-bit parallel-output ADC with similar resolution and speed, usable as an alternative when the original LTC1416IG is unavailable.
  • AD7874ANZ --: Pin-compatible 14-bit successive-approximation ADC with similar speed and parallel interface, widely available from an alternate vendor.
  • MAX125CCAX+ --: 14-bit multi-channel ADC with comparable sampling rate and parallel output, suitable as a functional substitute in many designs.
  • ADS7816U --: 12-bit serial ADC offering similar resolution class and low power, usable when slight resolution reduction is acceptable.
