LTC1044 Datasheet Switched Capacitor Voltage Converter

Manufacturer: Analog Devices

Overview: LTC1044/7660 Switched Capacitor Voltage Converter.

General 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
