Description and Introduction

315MHz Low-Power, +3V Superheterodyne Receiver The **MAX1470EUI+T** is a highly integrated, low-power CMOS superheterodyne receiver designed for **315MHz** and **433.92MHz** frequency bands.  

### **Manufacturer:**  
- **Maxim Integrated** (now part of Analog Devices)  

### **Key Specifications:**  
- **Frequency Range:** 300MHz to 450MHz  
- **Modulation Types:** ASK (Amplitude-Shift Keying)  
- **Supply Voltage:** 2.7V to 3.6V  
- **Current Consumption:**  
  - **Active Mode:** 5.3mA (typical)  
  - **Shutdown Mode:** 0.5µA (typical)  
- **Sensitivity:** -114dBm (for 433.92MHz, 10kbps data rate)  
- **IF Frequency:** 10.7MHz  
- **Data Rate:** Up to 100kbps  
- **Package:** 28-pin TSSOP (MAX1470EUI+T)  

### **Features:**  
- **Low-Power Operation:** Suitable for battery-powered applications.  
- **Integrated IF Filter:** Eliminates the need for external SAW filters.  
- **Automatic Gain Control (AGC):** Enhances dynamic range.  
- **RSSI Output:** Provides received signal strength indication.  
- **Wake-Up Timer:** Enables power-saving modes.  
- **Single-Crystal Oscillator:** Supports both RF and baseband functions.  

### **Applications:**  
- **Remote Keyless Entry (RKE)**  
- **Wireless Sensors**  
- **Home Automation**  
- **Industrial Controls**  

This receiver is optimized for low-power, cost-sensitive wireless applications.

Application Scenarios & Design Considerations

315MHz Low-Power, +3V Superheterodyne Receiver

Alternative Part Number

  • MAX1470EUI --: Same base device in the same 28-pin TSSOP package without the tape-and-reel suffix; functionally identical and widely available.
  • MAX1471EUI --: Closely related Maxim 300MHz-450MHz receiver in the same package family, suitable as a functional substitute with minor configuration differences.
  • MAX1473EUI --: Another Maxim receiver IC in the same TSSOP package and frequency range, usable as an alternative when the exact MAX1470 variant is unavailable.
  • TDA5201 --: Single-chip ASK/FSK receiver in the 300-450 MHz range, functionally similar to the MAX1470 low-power receiver and widely used as a drop-in alternative.
  • MICRF211 --: Low-power ASK/OOK receiver IC covering similar frequency bands with comparable sensitivity, suitable replacement for short-range RF receive applications.
  • RX3400 --: Compact ASK receiver module offering similar low-power receive functionality for 433 MHz applications, usable as an alternative in designs based on the MAX1470.
