Description and Introduction

500ksps, 12-Bit ADCs with Track/Hold And Refrence The MAX120CNG is a 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Sampling Rate:** Up to 500 kSPS (kilo-samples per second)  
- **Input Channels:** 8 single-ended or 4 differential  
- **Input Voltage Range:** 0V to VREF (programmable reference)  
- **Reference Voltage:** External (2.5V to VDD)  
- **Power Supply:** +5V single supply  
- **Conversion Time:** 2.2 µs (typical)  
- **Interface:** Parallel (8-bit or 12-bit selectable)  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)  
- **Package:** 24-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The MAX120CNG is a successive-approximation ADC with an internal track/hold circuit.  
- It offers high-speed, low-power performance suitable for industrial control, data acquisition, and instrumentation applications.  
- The device supports both single-ended and differential input configurations.  

### **Features:**  
- **Low Power Consumption:** 60 mW (typical) at 500 kSPS  
- **Internal Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Flexible Input Configuration:** Supports 8 single-ended or 4 differential inputs.  
- **Adjustable Reference:** Allows use of an external reference (2.5V to VDD).  
- **Parallel Output:** 8-bit or 12-bit selectable for interfacing with microprocessors.  
- **No Missing Codes:** Guaranteed over the full operating temperature range.

Application Scenarios & Design Considerations

500ksps, 12-Bit ADCs with Track/Hold And Refrence

Alternative Part Number

  • AD1674JN --: Pin-compatible 12-bit successive-approximation ADC with similar sampling rate and parallel interface, widely used as a direct substitute.
  • ADS7805P --: 12-bit 100 kSPS sampling ADC in a DIP package with a parallel interface, offering comparable performance and easy board-level replacement.
  • LTC1278CN --: 12-bit 400 kSPS ADC with parallel output and similar analog input range, suitable as a higher-speed alternative in the same footprint class.
  • AD1674JNZ --: Pin-compatible 12-bit successive-approximation ADC with similar sampling rate and parallel interface, widely used as a direct MAX120 replacement.
