Description and Introduction

265ksps / +3V / 6-/2-Channel / 12-Bit ADCs with +2.5V Reference and Parallel Interface The MAX1297ACEG is a 12-bit, low-power, successive approximation 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:** +5V (analog), +2.7V to +5.25V (digital)  
- **Conversion Time:** 3µs (max)  
- **Sampling Rate:** Up to 250ksps  
- **Power Consumption:**  
  - 6.5mW (at 250ksps, +5V supply)  
  - 1.5mW (at 50ksps, +3V supply)  
- **Input Voltage Range:** 0V to VREF (single-ended), ±VREF (differential)  
- **Reference Voltage:** Internal (4.096V) or external (1V to VDD)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin QSOP  

### **Descriptions:**
- The MAX1297ACEG is a high-speed, low-power, 12-bit ADC with an internal track/hold, voltage reference, and serial interface.  
- It supports both single-ended and differential input configurations.  
- Designed for battery-powered and data acquisition applications requiring high-speed conversions with minimal power consumption.  

### **Features:**  
- **Low Power:** Auto-shutdown mode reduces power consumption when idle.  
- **Flexible Input Configuration:** Supports 8 single-ended or 4 differential inputs.  
- **Internal Reference:** 4.096V reference with low drift (15ppm/°C typical).  
- **High-Speed Serial Interface:** SPI-compatible for easy microcontroller interfacing.  
- **Software-Configurable:** Unipolar/bipolar, single-ended/differential modes.  
- **Small Footprint:** 24-pin QSOP package for space-constrained designs.  

This ADC is commonly used in industrial control, medical instruments, and portable data logging systems.  

(Note: Always refer to the official datasheet for the most accurate and updated information.)
