Description and Introduction

308Ksps ADC with DSP Interface and 78dB SINAD The MAX121EWE is a high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Resolution:** 12-bit  
- **Sampling Rate:** 1.5 MSPS (Mega Samples Per Second)  
- **Input Voltage Range:** ±5V (Bipolar), 0V to +5V (Unipolar)  
- **Power Supply:** ±5V  
- **Power Consumption:** 175mW (typical)  
- **DNL (Differential Non-Linearity):** ±0.5 LSB (max)  
- **INL (Integral Non-Linearity):** ±1 LSB (max)  
- **Signal-to-Noise Ratio (SNR):** 72dB (typical)  
- **Total Harmonic Distortion (THD):** -80dB (typical)  
- **Package:** 16-pin Wide SOIC (SO-16)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MAX121EWE is a high-performance, 12-bit ADC designed for applications requiring fast and accurate data conversion.  
- It features a successive approximation register (SAR) architecture for high-speed conversion.  
- The device supports both unipolar and bipolar input ranges, making it versatile for various signal processing applications.  

### **Features:**
- **High-Speed Conversion:** 1.5 MSPS throughput.  
- **Low Power Consumption:** 175mW typical operation.  
- **Wide Input Range:** Supports ±5V bipolar and 0V to +5V unipolar inputs.  
- **Internal Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Parallel Digital Output:** 12-bit parallel interface for easy interfacing with microprocessors.  
- **No Missing Codes Guaranteed:** Ensures accurate conversion across the full temperature range.  
- **Single +5V and -5V Supply Operation:** Simplifies power supply design.  
- **Robust Performance:** Excellent SNR and THD for precision applications.  

This information is based on the manufacturer's datasheet and technical documentation.
