DESCRIPTIO
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.
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.
