Description and Introduction

500ksps, Sampling, 12-Bit ADC with Track/Hold and Reference The MAX120EAG+ is a high-performance, 12-bit analog-to-digital converter (ADC) manufactured by **MAXIM Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Sampling Rate:** 500 kSPS (kilo-samples per second)  
- **Input Voltage Range:** ±10V, ±5V, or 0 to +10V (software-selectable)  
- **Power Supply:** ±5V  
- **Power Consumption:** 100mW (typical)  
- **Interface:** Parallel (8-bit or 12-bit bus)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**  
- The MAX120EAG+ is a **successive approximation register (SAR) ADC** with **internal track/hold**, eliminating the need for an external sample-and-hold circuit.  
- It features **software-selectable input ranges**, allowing flexibility in signal acquisition.  
- Designed for **high-speed, precision data acquisition** in industrial, medical, and instrumentation applications.  

### **Features:**  
- **True Bipolar Input Range** (±10V, ±5V) and **Unipolar Input Range** (0 to +10V).  
- **Low Power Consumption** (100mW typical).  
- **Internal 2.5V Reference** (with external reference option).  
- **No Missing Codes** over the full temperature range.  
- **Fast Conversion Time:** 1.6µs (typical).  
- **Parallel Data Output** (8-bit or 12-bit bus).  
- **Robust Design:** Operates in extended industrial temperature ranges (-40°C to +85°C).  

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

Application Scenarios & Design Considerations

500ksps, Sampling, 12-Bit ADC with Track/Hold and Reference

Alternative Part Number

  • AD1674JNZ --: Pin-compatible 12-bit successive-approximation ADC with similar sampling rate and parallel interface, widely used as a direct substitute in the same socket.
  • ADS7805U --: 12-bit 100 kSPS sampling ADC with comparable parallel output and reference architecture, suitable replacement with minor layout review.
  • LTC1278CN --: 12-bit 400 kSPS ADC offering similar functionality and interface, usable as an upgrade alternative when higher throughput is acceptable.
