Description and Introduction

Complete / Isolated RS-485/RS-422 Data Interface The MAX1490AEPG is a high-performance, 16-bit, serial-output analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 16-bit  
- **Sampling Rate:** 250 kSPS (kilosamples per second)  
- **Input Voltage Range:** ±10V (bipolar) or 0V to +10V (unipolar)  
- **Interface:** Serial (SPI/QSPI/MICROWIRE compatible)  
- **Power Supply:** Single +5V or dual ±5V  
- **Power Consumption:** 110mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin PDIP (Plastic Dual In-line Package)  

### **Descriptions:**
- The MAX1490AEPG is a precision ADC designed for high-accuracy data acquisition systems.  
- It includes an internal track-and-hold (T/H) circuit, eliminating the need for an external sample-and-hold amplifier.  
- The device supports both unipolar and bipolar input ranges, making it versatile for industrial and instrumentation applications.  
- It features a serial interface for easy integration with microcontrollers and digital signal processors (DSPs).  

### **Features:**
- **16-Bit Resolution** – Ensures high-precision analog signal conversion.  
- **Low Noise & High Linearity** – Provides accurate signal acquisition.  
- **Flexible Input Range** – Supports both unipolar (0V to +10V) and bipolar (±10V) modes.  
- **Internal T/H Circuit** – Simplifies external circuitry requirements.  
- **SPI-Compatible Serial Interface** – Allows easy interfacing with microcontrollers.  
- **Low Power Consumption** – Suitable for power-sensitive applications.  
- **Wide Operating Temperature Range** (-40°C to +85°C) – Ideal for industrial environments.  

This information is based solely on the manufacturer's datasheet for the MAX1490AEPG.
