LTC6900CS5#TRPBF

The LTC6900CS5#TRPBF from Analog Devices is a precision, low-power, silicon programmable oscillator designed for ease of use and minimal board space. Its frequency is set by a single external resistor, allowing for high accuracy operation without external trim components.

This oscillator operates from 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 and fall times. The frequency range spans from 1kHz to 20MHz, programmable via an external resistor and a three-state DIV input that divides the master clock by 1, 10, or 100.

Key electrical specifications include a typical supply current of 500μA at 3V and 3MHz, frequency errors of ≤1.5% max at 25°C and ≤2% max over 0°C to 70°C, and a temperature stability of ±40ppm/°C. The device also features a supply stability of 0.04%/V and a fast start-up time between 50μs and 1.5ms.

The LTC6900CS5#TRPBF is available in a low-profile SOT-23-5 Thin package, making it suitable for portable and battery-powered equipment such as PDAs and cell phones. It serves as a low-cost, precision oscillator replacement for fixed crystal or ceramic oscillators and can be used as a clock reference for switching power supplies or charge pump drivers.
