The MAX7384 is a dual-speed silicon oscillator produced by Texas Instruments. It is used in 3V, 3.3V, and 5V circuits and has high accuracy, anti-interference, and low power consumption. It can be used in home appliances, industrial, and automotive applications.
The MAX7384 is a dual‑speed silicon oscillator that replaces ceramic resonators, crystals, and crystal‑oscillator modules as the primary and secondary clock source for microcontrollers in 3 V, 3.3 V, and 5 V applications. It provides a high‑speed clock (10 MHz‑16 MHz) and a low‑speed 32.768 kHz clock, with glitch‑free switching and an integrated power‑on‑reset supervisor.
The device operates from –40 °C to +125 °C, delivers up to +10 mA clock‑output drive, and offers low jitter (80 ps p‑p at 16 MHz) and low power consumption (4 mA at 16 MHz, 13 µA at 32 kHz). Pin functions, electrical characteristics, and typical application circuits are provided for easy integration into consumer, automotive, and industrial products.
