Description and Introduction

GSM PA Drain Controller for Dual Band Cellular Subscriber Terminal The MC33170 is a series of operational amplifiers (op-amps) manufactured by Motorola. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
1. **Supply Voltage Range:**  
   - Single Supply: 3.0V to 44V  
   - Dual Supply: ±1.5V to ±22V  

2. **Input Offset Voltage:**  
   - Typically 2.0mV (max 7.0mV)  

3. **Input Bias Current:**  
   - Typically 25nA (max 100nA)  

4. **Input Offset Current:**  
   - Typically 5.0nA (max 50nA)  

5. **Common-Mode Rejection Ratio (CMRR):**  
   - Typically 100dB (min 70dB)  

6. **Power Supply Rejection Ratio (PSRR):**  
   - Typically 100dB (min 70dB)  

7. **Gain Bandwidth Product (GBW):**  
   - 1.4MHz  

8. **Slew Rate:**  
   - 0.4V/µs  

9. **Output Current:**  
   - Typically 30mA  

10. **Operating Temperature Range:**  
    - Commercial (0°C to +70°C)  
    - Industrial (-40°C to +85°C)  

### **Descriptions:**
- The MC33170 is a low-power, high-performance operational amplifier designed for single or dual-supply operation.  
- It is optimized for battery-powered applications due to its low quiescent current (typically 180µA per amplifier).  
- The device features internal frequency compensation and short-circuit protection.  
- It is available in multiple package options, including DIP, SOIC, and surface-mount packages.  

### **Features:**
1. Low power consumption (180µA per amplifier typical).  
2. Wide supply voltage range (3V to 44V single supply).  
3. High input impedance.  
4. Internal frequency compensation.  
5. Short-circuit protected output.  
6. Low input offset voltage and bias current.  
7. High common-mode rejection ratio (CMRR).  
8. High power supply rejection ratio (PSRR).  

This information is based on Motorola's official documentation for the MC33170 series.

Application Scenarios & Design Considerations

GSM PA Drain Controller for Dual Band Cellular Subscriber Terminal

Alternative Part Number

  • LM358N --: Dual operational amplifier in DIP-8 with similar general-purpose specs, widely available and pin-compatible in most circuits.
  • TL072CP --: Low-noise JFET-input dual op-amp, common drop-in replacement for general-purpose op-amp applications with better input impedance.
  • NE5532P --: Dual low-noise op-amp with higher output drive, suitable alternative when improved audio performance is acceptable.
