Description and Introduction

N-Channel 40-V (D-S) MOSFET The SI4840DY-T1 is a radio tuner IC manufactured by Silicon Laboratories (SI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Silicon Laboratories (SI)  

### **Part Number:**  
SI4840DY-T1  

### **Description:**  
The SI4840DY-T1 is a fully integrated AM/FM/SW radio tuner IC designed for portable and consumer radio applications. It incorporates a digital low-IF receiver architecture, eliminating the need for external IF filters and reducing component count.  

### **Key Features:**  
- **Frequency Range:**  
  - AM: 520–1710 kHz  
  - FM: 64–108 MHz  
  - SW: 2.3–30 MHz (optional)  
- **Digital Tuning:**  
  - Supports both analog and digital tuning interfaces  
  - 10 Hz tuning resolution  
- **Low Power Consumption:**  
  - Operates from 2.7V to 5.5V supply  
  - Low standby current  
- **Integrated Audio Processing:**  
  - Built-in stereo audio processing  
  - Automatic gain control (AGC)  
  - Soft mute and noise blanking  
- **Digital Interface:**  
  - I²C control interface  
  - Supports RDS/RBDS (FM only)  
- **Package:**  
  - 20-pin SOIC (Small Outline Integrated Circuit)  

### **Applications:**  
- Portable radios  
- Home audio systems  
- Automotive infotainment  
- Consumer electronics
