FM receiver circuit for battery supply The TDA7088 is an integrated circuit (IC) manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:
### **Specifications:**
1. **Function:** FM Radio Receiver IC
2. **Frequency Range:** Typically 88–108 MHz (FM band)
3. **Supply Voltage:** 1.8V to 5V (low-voltage operation)
4. **Current Consumption:** Low power consumption (~5mA typical)
5. **Package:** SOP16 (Small Outline Package, 16 pins)
6. **Sensitivity:** High sensitivity for weak signal reception
7. **IF Frequency:** No external IF filter required (fully integrated)
8. **Mute Function:** Built-in mute control for noise suppression
9. **Search Tuning:** Automatic station search and lock feature
10. **Stereo Output:** No (mono output only)
### **Descriptions:**
- The TDA7088 is a monolithic FM radio receiver IC designed for portable applications.
- It integrates all necessary functions (RF amplifier, mixer, PLL, IF limiter, and demodulator) into a single chip.
- Requires minimal external components, making it suitable for compact designs.
- Operates without a traditional tuning knob; uses electronic tuning via buttons (up/down search).
- Includes an AFC (Automatic Frequency Control) for stable reception.
### **Features:**
1. **Fully Integrated:** No external IF coil or filter needed.
2. **Low Voltage Operation:** Works efficiently at 1.8V, ideal for battery-powered devices.
3. **Automatic Station Search:** Scans and locks onto FM stations.
4. **Mute Function:** Eliminates noise during tuning.
5. **Compact Design:** Small footprint with minimal external components.
6. **Wide Supply Range:** Supports 1.8V–5V DC.
7. **No Manual Tuning:** Uses electronic search instead of variable capacitors.
