Description and Introduction

+5V to ±10V Voltage Converters The MAX680CSA+ is a dual charge-pump voltage converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX680CSA+  
- **Type:** Dual Charge-Pump Voltage Converter  
- **Package:** 8-Pin SOIC  
- **Operating Voltage Range:** 1.5V to 6V  
- **Output Voltage:** ±5V (with 5V input) or adjustable  
- **Output Current:** Up to 10mA (per output)  
- **Switching Frequency:** 10kHz (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Efficiency:** Up to 99% (typical)  

### **Descriptions:**
The MAX680CSA+ is a dual charge-pump DC-DC converter that generates both positive and negative voltages from a single input supply. It eliminates the need for inductors, making it suitable for space-constrained applications. The device is commonly used in low-power systems requiring bipolar supplies, such as data acquisition, portable instruments, and RS-232 interfaces.

### **Features:**
- **Dual Output:** Generates both positive and negative voltages.  
- **No Inductors Required:** Uses only external capacitors.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Wide Input Voltage Range:** Operates from 1.5V to 6V.  
- **High Efficiency:** Up to 99% conversion efficiency.  
- **Simple External Components:** Requires only four capacitors.  
- **Low Output Impedance:** Ensures stable voltage regulation.  
- **Compact Package:** 8-pin SOIC for space-saving designs.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

+5V to ±10V Voltage Converters

Alternative Part Number

  • ICL7660CPA+ --: Pin-compatible charge-pump voltage converter in the same 8-pin DIP package, widely used as a drop-in substitute for the MAX680 in similar inverter/doubler applications.
  • LT1054CN8 --: Switched-capacitor voltage converter with higher output current and similar function, available in 8-pin DIP, suitable replacement when extra drive capability is acceptable.
  • TC7660CPA --: Low-cost CMOS charge-pump voltage converter in 8-pin DIP with comparable inverter/doubler operation, good second-source option for non-critical designs.
  • LTC1144CS8#PBF --: Pin-compatible switched-capacitor voltage converter in an 8-pin SOIC package with similar inverting/doubling function and supply range.
  • ICL7660CSA+ --: Classic charge-pump voltage converter in SOIC-8 offering comparable voltage inversion and multiplication capability.
  • TC7660EOA --: SOIC-8 charge-pump converter with similar voltage inversion/doubling behavior and wide supply range, suitable as a functional substitute.
