5V to 9V nn East to Use nn Commercial Device Guaranteed Over –40°C to 85°C Temperature Range APPLICATIONS nn Conversion of 5V to ±5V Supplies nn Precise Voltage Division, VOUT = VIN/2 ±20ppm nn Voltage Multiplication, VOUT = ±nVIN nn Supply Splitter, VOUT = ±VS/2 DESCRIPTION The LTC®1044 is a monolithic CMOS switched capacitor voltage converter which is manufactured using Analog Devices’ enhanced LTCMOS™ silicon gate process.
The LTC1044 provides several voltage conversion functions: the input voltage can be inverted (VOUT = –VIN), doubled (VOUT = 2VIN), divided (VOUT = VIN/2) or multiplied (VOUT = ± nVIN).
Designed to be pin-for-pin and functionally compatible with the popular 7660, the LTC1044 provides significant features and improvements over earlier 7660 designs.
These improvements include: full 1.
5V to 9V supply operation over the entire operating temperature range, without the need for external protection diodes; two and one-half times lower quiescent current for greater power conversion efficiency; and a “boost” function which is available to raise the internal oscillator frequency to optimize performance in specific applications.
Although the LTC1044 provides significant design and performance advantages over the earlier 7660 device, it still maintains its compatibility with existing 7660 designs.
