2x4-Channel, Simultaneous-Sampling, 14-Bit DAS The MAX125CEAX+D is a high-speed, multichannel, simultaneous-sampling 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 information:
### **Specifications:**
- **Resolution:** 14-bit
- **Channels:** 4 simultaneous sampling channels
- **Sampling Rate:** Up to **1.25 MSPS (Million Samples Per Second)** per channel
- **Input Voltage Range:** ±10V (bipolar)
- **Power Supply:** ±5V
- **DNL (Differential Nonlinearity):** ±1 LSB (max)
- **INL (Integral Nonlinearity):** ±2 LSB (max)
- **Signal-to-Noise Ratio (SNR):** 78dB (typical)
- **Total Harmonic Distortion (THD):** -85dB (typical)
- **Operating Temperature Range:** **0°C to +70°C** (commercial grade)
- **Package:** **36-pin SSOP (Shrink Small Outline Package)**
### **Descriptions:**
- The MAX125CEAX+D is designed for high-speed, precision data acquisition systems.
- It integrates four **track-and-hold (T/H) amplifiers**, enabling simultaneous sampling of multiple channels.
- It features an **internal reference voltage** (4.096V) but also supports an external reference.
- The ADC is optimized for applications requiring high dynamic performance, such as industrial automation, medical imaging, and power monitoring.
### **Features:**
- **Simultaneous Sampling:** All four channels are sampled at the same instant.
- **High-Speed Parallel Interface:** Allows fast data transfer to microprocessors or DSPs.
- **Low Power Consumption:** Typically **500mW** (±5V supply).
- **On-Chip T/H Amplifiers:** Eliminates the need for external sample-and-hold circuits.
- **Flexible Input Range:** Accepts both **unipolar (0 to +10V)** and **bipolar (±10V)** signals.
- **Internal or External Reference:** Supports system calibration flexibility.
