Description and Introduction

265ksps / +3V / 6-/2-Channel / 12-Bit ADCs with +2.5V Reference and Parallel Interface The MAX1297BCEG is a 12-bit, low-power, serial analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Supply Voltage:** +2.7V to +5.25V  
- **Power Consumption:**  
  - 1.5mA (operating mode)  
  - 2µA (power-down mode)  
- **Sampling Rate:** Up to 133ksps  
- **Interface:** SPI/QSPI/MICROWIRE-compatible 3-wire serial  
- **Input Voltage Range:** 0V to VREF (unipolar) or ±VREF/2 (bipolar)  
- **Reference Voltage:** Internal 4.096V or external (1V to VDD)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin QSOP  

### **Descriptions:**  
The MAX1297BCEG is a low-power, multichannel ADC designed for precision data acquisition in battery-powered and space-constrained applications. It features a successive-approximation register (SAR) architecture and includes a built-in reference, track/hold, and serial interface for easy microcontroller integration.  

### **Features:**  
- **Low Power Consumption:** Ideal for portable and battery-operated devices.  
- **Flexible Input Configuration:** Supports both single-ended and differential inputs.  
- **Internal/External Reference:** Built-in 4.096V reference or accepts an external reference.  
- **High-Speed SPI Interface:** Enables fast communication with microcontrollers.  
- **Software-Configurable:** Unipolar or bipolar input modes.  
- **Power-Down Mode:** Reduces current consumption to 2µA when idle.  

This device is commonly used in industrial control, medical instrumentation, and portable data logging systems.
