Description and Introduction

Multirange, +5V, 8-Channel, Serial 12-Bit ADCs The MAX1271AEAI+ is a 12-bit, multichannel, successive approximation analog-to-digital converter (ADC) manufactured by **MAXIM/DALLAS**.  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial  
- **Supply Voltage:** +5V  
- **Sampling Rate:** Up to 110ksps  
- **Input Voltage Range:**  
  - **Single-Ended Mode:** 0V to VREF  
  - **Differential Mode:** ±VREF  
- **Reference Voltage:** Internal (4.096V) or external (1V to VDD)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP  

### **Descriptions and Features:**  
- **High-Speed Conversion:** Achieves 110ksps throughput.  
- **Low Power Consumption:** 2.5mA (operating), 2µA (shutdown).  
- **Flexible Input Configuration:** Supports both single-ended and differential inputs.  
- **Internal or External Reference:** Includes a 4.096V internal reference or allows external reference input.  
- **SPI-Compatible Serial Interface:** Simplifies microcontroller interfacing.  
- **Software-Configurable Unipolar/Bipolar Modes:** Allows ±VREF operation in differential mode.  
- **Auto-Shutdown Mode:** Reduces power consumption when not in use.  
- **On-Chip Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  

This ADC is suitable for industrial control, data acquisition, and instrumentation applications.

Application Scenarios & Design Considerations

Multirange, +5V, 8-Channel, Serial 12-Bit ADCs

Alternative Part Number

  • AD7874ANZ --: 12-bit successive-approximation ADC with similar parallel interface and throughput, pin-compatible in many designs and widely available.
  • LTC1272CCN --: 12-bit 250ksps ADC with parallel output, functionally equivalent to the MAX1271 family and a common drop-in substitute.
  • ADS7841E --: 12-bit SAR ADC with serial interface; suitable alternative when interface flexibility is acceptable and offers good cost and availability.
  • LTC1272CN8 --: 12-bit 250ksps sampling ADC with comparable resolution and speed, different naming and series, usable as an alternative with minor interface adaptation.
  • ADS7805U --: 12-bit parallel-output ADC offering similar resolution and conversion performance, from a distinct series, providing a viable cross-manufacturer option.
