Description and Introduction

15kV ESD-Protected / EMC-Compliant / 230kbps / 3-Tx/3-Rx RS-232 IC The MAX1406EWE is a multichannel, low-power, 16-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 16-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Sampling Rate:** Up to 480 samples per second (sps)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Supply Voltage:** +2.7V to +3.6V (analog), +1.8V to +3.6V (digital)  
- **Power Consumption:** 1.5mA (operating), 1µA (shutdown)  
- **Input Voltage Range:** 0V to VREF (programmable)  
- **Reference Voltage:** Internal (2.5V) or external (up to VDD)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (WE)  

### **Descriptions:**  
The MAX1406EWE integrates a 16-bit sigma-delta ADC with a flexible input multiplexer, PGA (programmable gain amplifier), and digital filtering. It is designed for low-power, high-precision applications such as industrial sensors, medical instruments, and portable data acquisition systems.  

### **Features:**  
- **Low Power:** 1.5mA operating current, 1µA shutdown mode  
- **Programmable Gain (PGA):** 1x to 128x  
- **On-Chip Calibration:** System offset and full-scale calibration  
- **Digital Filtering:** Adjustable sinc filter for noise reduction  
- **Flexible Input Configuration:** Single-ended or differential inputs  
- **Internal Oscillator:** No external clock required  
- **SPI-Compatible Interface:** Simplifies microcontroller interfacing

Application Scenarios & Design Considerations

15kV ESD-Protected / EMC-Compliant / 230kbps / 3-Tx/3-Rx RS-232 IC

Alternative Part Number

  • ADM202EARNZ --: Pin-compatible RS-232 transceiver with similar dual-driver/receiver function and ESD protection, widely available and often used as a MAX1406 substitute.
  • SP202ECN-L --: Low-power RS-232 transceiver in the same SOIC-16 footprint, functionally equivalent to the MAX1406 with comparable data rate and supply voltage.
  • ST202ECDR --: Dual RS-232 driver/receiver in SOIC-16 package offering similar electrical characteristics and a cost-effective drop-in alternative.
