The LT1026 is a switched capacitor voltage doubler and inverter on a single monolithic die from Linear Technology Corporation. It can operate from a 4V to 10V input and 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. The LT1026 offers a convenient way of generating additional system voltages without using inductors. Powering interface circuits, op amps or data acquisition circuitry off logic supplies is simplified.
The Linear Technology LT1026 is an 8-pin monolithic integrated circuit designed to generate both positive and negative output voltages from a single input supply. It functions as a switched capacitor voltage doubler followed by an inverter, capable of operating with inputs between 4V and 10V to provide outputs up to ±18V.
