Description and Introduction

14-Bit, 135ksps, Single-Supply ADCs with Bipolar Analog Input Range The **MAX1174BCUP+** is a high-performance, 12-bit analog-to-digital converter (ADC) manufactured by **MAXIM/DALLAS**. Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Sampling Rate:** 1.5Msps (Mega samples per second)  
- **Input Channels:** 8 single-ended or 4 differential  
- **Supply Voltage:** +5V (analog), +2.7V to +5.25V (digital)  
- **Power Consumption:** 37mW (typical at 1.5Msps)  
- **DNL (Differential Non-Linearity):** ±0.5 LSB (max)  
- **INL (Integral Non-Linearity):** ±1 LSB (max)  
- **Signal-to-Noise Ratio (SNR):** 70dB (typical)  
- **THD (Total Harmonic Distortion):** -85dB (typical)  
- **Interface:** Parallel (8-bit or 12-bit)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-TSSOP  

### **Descriptions:**  
- The **MAX1174BCUP+** is a low-power, high-speed, 12-bit ADC designed for precision data acquisition.  
- It features an internal track-and-hold (T/H) circuit and a reference buffer, eliminating the need for external components in many applications.  
- Suitable for industrial control, medical instrumentation, and communications systems.  

### **Features:**  
- **High-Speed Conversion:** 1.5Msps throughput.  
- **Flexible Input Configuration:** Supports single-ended or differential inputs.  
- **Low Power:** 37mW typical power consumption.  
- **Internal Reference:** 2.048V or 4.096V selectable reference.  
- **Parallel Interface:** Allows easy interfacing with microcontrollers and DSPs.  
- **Wide Digital Supply Range:** Compatible with 3V or 5V logic.  
- **Power-Down Mode:** Reduces power consumption when inactive.
