Product Summary

The LTC1261CS8-4#TR is a switched-capacitor voltage inverter designed to provide a regulated negative voltage from a single positive supply. The LTC1261CS operates from a single 3V to 8V supply and provides an adjustable output voltage from -1.25V to -8V. An on-chip resistor string allows the LTC1261CS8-4#TR to be configured for output voltages of -3.5V, -4V, -4.5V or -5V with no external components. The applications of the LTC1261CS8-4#TR include GaAs FET Bias Generators, Negative Supply Generators, Battery-Powered Systems, Single Supply Applications.
