ICL7660AIBAZA-T

ICL7660AIBAZA-T is a super voltage converter. It is a monolithic CMOS voltage conversion IC that ensures significant performance advantages over other similar devices. They are direct replacements for the industry standard ICL7660 offering an extended operating supply voltage range up to 12V, with a lower supply current. A frequency Boost pin has been incorporated to enable the user to achieve lower output impedance despite using smaller capacitors. It performs supply voltage conversions from positive to negative for an input range of 1.5V to 12V, resulting in complementary output voltages of -1.5V to -12V. Only two non-critical external capacitors are needed, for the charge pump and charge reservoir functions. The application includes simple conversion of +5V to ±5V supplies, voltage multiplication VOUT = ±nVIN, negative supplies for data acquisition systems and instrumentation, RS232 power supplies, supply splitter (VOUT = ±VS).
