MAX7375AXR105+T

The MAX7375AXR105+T is a fully integrated silicon oscillator from Analog Devices Inc./Maxim Integrated, factory-trimmed to a nominal frequency of 1 MHz. It provides a rail-to-rail CMOS square-wave output with a 50% duty cycle, requiring no external timing components. The oscillator operates over a wide supply voltage range of 2.7V to 5.5V and draws a typical supply current of 1.1 mA at 5V.

Key electrical characteristics include a typical initial accuracy of 2% at 25°C, a temperature drift of ±50 ppm/°C, and a fast startup time of 5 µs. The output features a typical rise/fall time of 5 ns and a maximum duty cycle of 40% to 60%. Peak-to-peak jitter is typically 160 ps at 8 MHz. The device is designed for low EMI susceptibility and high immunity to vibration and humidity, making it suitable for demanding environments.

The oscillator is offered in a compact 3-pin SC-70-3 surface-mount package measuring 2.20 mm x 1.35 mm x 1.10 mm. It is rated for an operating temperature range of -40°C to +125°C. The MAX7375 series is intended as a low-cost upgrade for ceramic resonators, crystals, and crystal oscillator modules in microcontroller and UART applications.
