Description and Introduction

500ksps, Sampling, 12-Bit ADC with Track/Hold and Reference The **MAX122BENG+** 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:

### **Specifications:**
- **Resolution:** 12-bit  
- **Sampling Rate:** Up to **1.5 MSPS (Million Samples Per Second)**  
- **Input Channels:** 8 single-ended or 4 differential  
- **Supply Voltage:** **±5V** (dual supply)  
- **Power Consumption:** **95mW** (typical)  
- **Interface:** Parallel  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **24-Pin PDIP (Plastic Dual In-line Package)**  
- **DNL (Differential Non-Linearity):** **±1 LSB (max)**  
- **INL (Integral Non-Linearity):** **±1 LSB (max)**  

### **Descriptions:**
- The **MAX122BENG+** is a **successive-approximation ADC** with **internal track/hold (T/H)** circuitry.  
- It features **low power consumption** and **high-speed conversion**, making it suitable for industrial and instrumentation applications.  
- The ADC includes a **precision reference** and **on-chip clock**, reducing external component requirements.  
- It supports both **single-ended** and **differential** input configurations.  

### **Features:**
- **12-bit resolution with no missing codes**  
- **Fast conversion time: 660ns**  
- **Internal 4.096V reference** (or external reference option)  
- **Wide input voltage range:** **±10V** (with ±5V supplies)  
- **Low power consumption:** **95mW (typical)**  
- **No pipeline delays**  
- **On-chip track/hold amplifier**  
- **Parallel data output** for easy interfacing  

This ADC is commonly used in **data acquisition systems, medical instruments, and industrial control systems**.  

*(Note: Maxim Integrated was acquired by Analog Devices in 2021, but legacy Maxim/Dallas parts remain available.)*

Application Scenarios & Design Considerations

Alternative Part Number

  • AD7870KN --: Pin-compatible 12-bit ADC with similar sampling performance and DIP-24 package, widely available as a direct functional substitute.
  • ADC674AJP --: 12-bit successive-approximation ADC with comparable conversion speed and parallel interface, suitable drop-in replacement in most designs.
  • LTC1272CN --: 12-bit ADC offering similar resolution and throughput in a DIP package, usable as an alternative when supply of the original is limited.
  • AD7874ANZ --: Pin-compatible 12-bit successive-approximation ADC with similar sampling and interface characteristics, widely available and well documented.
  • LTC1278CN --: 12-bit ADC in a comparable DIP package with similar conversion speed and parallel interface, suitable as a functional replacement.
  • ADS7805P --: 12-bit sampling ADC with similar resolution and parallel output interface, offering a viable alternative when the original is unavailable.
