DESCRIPTIO  
FEATURES  
The LT®1026 is a switched capacitor voltage doubler and  
inverter on a single monolithic die. Capable of operating  
from a 4V to 10V input, it provides ±7V to ±18V output.  
Output currents of over 10mA are available. Two charge  
pumps first double the input voltage then invert the  
doubled voltage. Manufactured in bipolar technology, the  
LT1026 is not susceptible to latchup and generates up to  
36V.  
Generates + and – from Single Input  
Up to ±18V Output  
Only Needs Four 1µF Capacitors  
No Inductors  
10mA Output Current Minimum  
Operates Down to 4V  
No Latchup  
8-Pin Minidip  
U
The LT1026 offers a convenient way of generating addi-  
tional system voltages without using inductors. Powering  
interface circuits, op amps or data acquisition circuitry off  
logic supplies is simplified. Other Linear Technology  
voltage converters such as the low power LTC® 1044  
CMOS and 100mA bipolar LT1054 are available.
