Description and Introduction

15kV ESD-Protected, Isolated RS-485/RS-422 The MAX1490EAEPG is a high-performance, 16-bit, serial-output analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 16-bit  
- **Interface:** Serial (SPI/QSPI™/MICROWIRE™ compatible)  
- **Sampling Rate:** Up to **250 kSPS** (kilo-samples per second)  
- **Input Voltage Range:** ±10V, ±5V, or 0 to +10V (programmable)  
- **Power Supply:** ±5V analog, +5V digital  
- **Power Consumption:** 150mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions and Features:**  
- **True Bipolar Input Range:** Supports ±10V, ±5V, or unipolar 0 to +10V inputs.  
- **High Accuracy:** ±2 LSB INL (Integral Nonlinearity) and ±1 LSB DNL (Differential Nonlinearity).  
- **Low Noise:** 92dB SNR (Signal-to-Noise Ratio) at 20kHz input frequency.  
- **On-Chip Calibration:** Includes self-calibration for zero and full-scale errors.  
- **Flexible Digital Interface:** Compatible with SPI, QSPI, and MICROWIRE serial interfaces.  
- **Internal/External Reference:** Supports both internal 4.096V reference and external reference options.  
- **Shutdown Mode:** Reduces power consumption when not in use.  
- **Robust Design:** Overvoltage protection on analog inputs.  

This ADC is commonly used in industrial, medical, and instrumentation applications requiring high-resolution data acquisition.

Application Scenarios & Design Considerations
