- **Input Voltage Range:** ±10V, ±5V, 0 to +10V (software-selectable)  
- **Power Supply:** Single +5V or dual ±5V  
- **Integral Nonlinearity (INL):** ±1 LSB (max)  
- **Differential Nonlinearity (DNL):** ±0.5 LSB (max)  
- **Signal-to-Noise Ratio (SNR):** 72 dB (typical)  
- **Total Harmonic Distortion (THD):** -80 dB (typical)  
- **Power Consumption:** 100 mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The MAX122BENG+ is a **successive-approximation ADC** with a built-in track/hold and reference.  
- It features **parallel digital outputs** for easy interfacing with microcontrollers or DSPs.  
- Designed for **high-speed, high-precision** applications such as industrial control, data acquisition, and instrumentation.  

### **Features:**  
- **Software-Configurable Input Ranges** (±10V, ±5V, 0 to +10V)  
- **No External Components Required** (includes internal reference and clock)  
- **Low Power Consumption** (100 mW typical)  
- **Wide Operating Temperature Range** (-40°C to +85°C)  
- **Parallel Interface** for easy system integration  
- **High Accuracy** with ±1 LSB INL and ±0.5 LSB DNL  

This ADC is suitable for applications requiring **high-speed, high-resolution conversions** with minimal external circuitry.
