LTC1799HS5#TRPBF

LTC1799HS5#TRPBF is a precision oscillator that is easy to use and occupies very little PC board space. The oscillator frequency is programmed by a single external resistor (RSET). It has been designed for high accuracy operation (≤1.5% frequency error) without the need for external trim components. It operates with a single 2.7V to 5.5V power supply and provides a rail-to-rail, 50% duty cycle square wave output. The CMOS output driver ensures fast rise/ fall times and rail-to-rail switching. The three-state DIV input determines whether the host clock is divided by 1, 10 or 100 before driving the output, providing three frequency ranges spanning 1kHz to 33MHz (5V supply). It is used in applications such as low cost precision oscillator, switching power supply clock reference, clocking switched capacitor filters, fixed crystal oscillator replacement, ceramic oscillator replacement.
