® SP782/784 Programmable Charge Pump s +5V Only Low Power Voltage Conversion s Programmable Between ±5V or ±10V s Low Power Shutdown Mode Applications s RS-232/RS-423 transceiver power supplies s LCD BIAS Generator s OP-Amp Power Supplies DESCRIPTION.
.
.
The SP782 and SP784 are monolithic programmable voltage converters that produce a positive and negative voltage from a single supply.
The SP782 and SP784 are programmable such that the charge pump outputs either a ±10V voltage or a ±5V voltage by control of two pins.
Both products require four (4) charge pump capacitors to support the resulting output voltages.
The charge pump architecture (U.
S.
5,760,637) is fabricated using a low power Bi...
