Description and Introduction

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters The MAX861ESA+T is a high-speed, low-power operational amplifier (op-amp) manufactured by **MAXIM Integrated** (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage Range:** ±4V to ±18V  
- **Input Offset Voltage:** 0.5mV (max)  
- **Input Bias Current:** 25nA (max)  
- **Gain Bandwidth Product (GBW):** 20MHz  
- **Slew Rate:** 10V/µs  
- **Quiescent Current:** 4.5mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The MAX861ESA+T is a precision, high-speed op-amp designed for applications requiring low noise and wide bandwidth.  
- It features low distortion and high slew rate, making it suitable for signal conditioning, data acquisition, and active filtering.  

### **Features:**  
- **Low Noise:** 6nV/√Hz at 1kHz  
- **Low Distortion:** -86dB THD at 20kHz  
- **Wide Bandwidth:** 20MHz GBW  
- **High Output Drive:** ±50mA output current  
- **Stable Operation:** Unity-gain stable  

This op-amp is commonly used in **medical instrumentation, audio processing, and test equipment** due to its high-speed performance and precision.  

(Note: Always refer to the latest datasheet for updated specifications.)

Application Scenarios & Design Considerations

50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters

Alternative Part Number

  • LTC1682CS8#PBF --: Pin-compatible low-noise charge pump inverter in SO-8 with similar output current and voltage range, widely available and a direct functional substitute.
  • ICL7660ACPA --: Classic charge pump voltage inverter offering comparable negative supply generation, though in DIP-8 package and requiring layout adjustment.
  • TC7660EOA --: Low-cost charge pump inverter with similar negative voltage conversion function, suitable as a drop-in style alternative with minor pinout verification.
  • LTC1685CS8#PBF --: Pin-compatible low-power comparator in SO-8 with similar supply range and response time, from the same corporate family after the Maxim acquisition.
  • TLV3201AIDBVR --: Rail-to-rail comparator with comparable propagation delay and supply voltage, suitable drop-in for many MAX861 applications.
  • LM393DR2G --: Widely available dual comparator in SOIC-8 with similar electrical characteristics; may require minor circuit adjustment but is a cost-effective substitute.
