Description and Introduction

4-/6-/8-Channel, 16-/14-Bit, Simultaneous-Sampling ADCs The **MAX11049ETN+** is a high-performance, 16-bit, 8-channel, simultaneous-sampling analog-to-digital converter (ADC) manufactured by **Maxim Integrated (now part of Analog Devices)**.  

### **Key Specifications:**  
- **Resolution:** 16-bit  
- **Channels:** 8 (simultaneous sampling)  
- **Sampling Rate:** Up to **500 kSPS** (per channel)  
- **Input Voltage Range:** ±10V (bipolar)  
- **Interface:** Serial Peripheral Interface (SPI)  
- **Power Supply:** ±5V (analog), +3V (digital)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 56-pin TQFN (7mm x 7mm)  

### **Features:**  
- **Simultaneous Sampling:** All 8 channels sampled at the same instant.  
- **High Accuracy:** Low INL (±2 LSB max) and DNL (±1 LSB max).  
- **Flexible Input Range:** Supports both unipolar (0 to +10V) and bipolar (±10V) modes.  
- **On-Chip Reference:** Includes a 4.096V internal reference (with external reference option).  
- **Low Power Consumption:** Typically **95mW** in normal operation.  
- **Digital Isolation Support:** Compatible with isolated SPI interfaces.  
- **Overvoltage Protection:** Up to ±16.5V on analog inputs.  

### **Applications:**  
- Power monitoring and control systems  
- Industrial automation and process control  
- Medical instrumentation  
- Data acquisition systems  

This ADC is designed for precision measurement applications requiring high channel count and simultaneous sampling.

Application Scenarios & Design Considerations

4-/6-/8-Channel, 16-/14-Bit, Simultaneous-Sampling ADCs

Alternative Part Number

  • AD7266BCPZ --: Dual 12-bit SAR ADC with similar channel count and throughput, pin-compatible style TQFN/LFCSP package, widely available and functionally comparable to the MAX11049.
  • LTC2308CUF --: 8-channel 12-bit SAR ADC with SPI interface, similar resolution and sampling rate, suitable drop-in functional replacement in many designs.
  • ADS7841E --: 4-channel 12-bit SAR ADC with serial interface, lower cost alternative offering comparable resolution and performance for less demanding channel-count applications.
  • AD7606BSTZ --: 8-channel 16-bit simultaneous-sampling ADC with similar functionality and performance, widely used as a direct alternative to Maxim multichannel ADCs.
  • ADS8588SIPM --: 8-channel 16-bit simultaneous-sampling bipolar-input ADC offering comparable specs and pin-compatible system design options.
  • LTC2348ILX-18 --: Octal 18-bit simultaneous-sampling ADC with similar channel count and interface, suitable as a higher-resolution substitute.
