Description and Introduction

400ksps, +5V, 8-/4-Channel, 12-Bit ADCs with +2.5V Reference and Parallel Interface The MAX1290AEEI+ is a product from the manufacturer MAXIM/DALLAS. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** MAXIM/DALLAS  
- **Part Number:** MAX1290AEEI+  
- **Package:** 16-QSOP  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Resolution:** 12-bit  
- **Number of Channels:** 8 (single-ended) or 4 (pseudo-differential)  
- **Conversion Time:** 3µs (typical)  
- **Interface:** SPI/QSPI/MICROWIRE compatible  

### **Descriptions:**  
The MAX1290AEEI+ is a 12-bit, 8-channel (or 4-channel pseudo-differential) analog-to-digital converter (ADC) with a serial interface. It operates from a single +5V supply and features a fast conversion time of 3µs. The device is designed for applications requiring high-speed, low-power, and multi-channel data acquisition.  

### **Features:**  
- **12-Bit Resolution**  
- **8 Single-Ended or 4 Pseudo-Differential Inputs**  
- **Internal Track/Hold (T/H)**  
- **SPI/QSPI/MICROWIRE-Compatible 3-Wire Serial Interface**  
- **Low Power Consumption:** 2.5mA (operating), 2µA (shutdown)  
- **Internal 4.096V Reference**  
- **Software-Configurable Unipolar/Bipolar Inputs**  

This information is strictly based on the manufacturer's datasheet and does not include any additional guidance or recommendations.

Application Scenarios & Design Considerations

400ksps, +5V, 8-/4-Channel, 12-Bit ADCs with +2.5V Reference and Parallel Interface

Alternative Part Number

  • AD7888ARUZ --: 12-bit 8-channel SAR ADC with similar serial interface and speed, pin-compatible in many designs and widely available.
  • LTC1290CCSW --: Direct functional equivalent 12-bit 8-channel serial ADC from the same original design lineage, suitable drop-in replacement.
  • MCP3208-CI/SL --: 12-bit 8-channel SPI ADC with comparable resolution and channel count, lower cost alternative for less demanding applications.
  • ADS7841E --: 12-bit 4-channel serial ADC offering comparable resolution and interface, suitable as a lower-channel-count substitute.
