LT1026

Voltage Converter

DESCRIPTIO

The LT

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. Other Linear Technology

voltage converters such as the low power LTC

CMOS and 100mA bipolar LT1054 are available.
