Description and Introduction

3Digit A/D Converters with Bandgap Refrence and Charge-Pump Voltage Converter The MAX138CPL is a microprocessor-compatible, 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated.  

### **Key Specifications:**  
- **Resolution:** 12 bits  
- **Conversion Time:** 3.5 µs (typical)  
- **Input Voltage Range:** ±10V, ±5V, 0 to +10V, or 0 to +5V (software selectable)  
- **Sampling Rate:** Up to 285 kSPS  
- **Interface:** Parallel, microprocessor-compatible  
- **Power Supply:** ±5V (analog), +5V (digital)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 40-pin PLCC  

### **Descriptions and Features:**  
- **True Bipolar Input Ranges:** Supports ±10V, ±5V, 0 to +10V, and 0 to +5V inputs.  
- **On-Chip Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **High-Speed Conversion:** 3.5 µs conversion time allows for fast data acquisition.  
- **Microprocessor Interface:** Directly interfaces with 8- or 16-bit microprocessors.  
- **Low Power Consumption:** Typically consumes 175 mW.  
- **Software-Configurable Input Range:** Simplifies system design by allowing range selection via software.  
- **No Missing Codes Guaranteed:** Ensures monotonicity over the full operating temperature range.  

This ADC is commonly used in industrial control, data acquisition systems, and instrumentation applications.
