Description and Introduction

420ksps / +5V / 6-/2-Channel / 12-Bit ADCs with +2.5V Reference and Parallel Interface The MAX1296BCEG is a 12-bit, multichannel, 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  
- **Sampling Rate:** Up to 100ksps (kilo samples per second)  
- **Input Voltage Range:** 0V to VREF (external reference)  
- **Supply Voltage:** +5V  
- **Power Consumption:** 5mW (typical)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 24-pin QSOP (Quarter Small Outline Package)  

### **Descriptions:**
- The MAX1296BCEG is a low-power, high-speed, 12-bit ADC with a built-in track-and-hold circuit.  
- It supports both single-ended and differential input configurations.  
- The device includes a precision reference input and operates with an external reference voltage.  
- It is designed for applications requiring high accuracy and low power consumption, such as data acquisition systems, industrial controls, and instrumentation.  

### **Features:**
- **Low Power:** 5mW typical power consumption.  
- **Flexible Input Configuration:** 8 single-ended or 4 differential inputs.  
- **High-Speed Serial Interface:** Compatible with SPI, QSPI, and MICROWIRE.  
- **Internal Track-and-Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Software-Configurable:** Allows selection of input channels and conversion modes.  
- **Small Package:** 24-pin QSOP for space-constrained applications.  

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

Application Scenarios & Design Considerations

420ksps / +5V / 6-/2-Channel / 12-Bit ADCs with +2.5V Reference and Parallel Interface

Alternative Part Number

  • AD7873ARUZ --: Pin-compatible 12-bit touchscreen ADC with similar SPI interface and supply range, widely available as a direct functional substitute.
  • TSC2046IPW --: Low-cost 12-bit touchscreen controller with SPI interface, functionally equivalent to the MAX1296 in touchscreen digitizer applications.
  • ADS7846E --: Industry-standard 12-bit touchscreen ADC with SPI interface, commonly used as a drop-in alternative to Maxim touchscreen controllers.
  • ADC108S022CIMTX/NOPB --: Similar low-power 10-bit serial ADC in a comparable package; pin/function compatible for many designs and widely available.
  • MCP3008-I/SL --: 10-bit SPI ADC with similar resolution and supply range; easy drop-in for low-speed data acquisition, though package and channel count should be verified.
  • LTC1286CS8#PBF --: 12-bit serial ADC offering equal or better resolution with similar serial interface; suitable upgrade path when board layout allows.
