ADIS16250/ADIS16255 is a low power gyroscope with digital range scaling, 14-bit digital gyroscope sensor outputs, 12-bit digital temperature sensor output, calibrated sensitivity and bias, in-system, auto-zero for bias drift calibration, digitally controlled sample rate, digitally controlled frequency response, dual alarm settings with configurable operation, embedded integration for short-term angle estimates, digitally activated self-test, digitally activated low power mode, interrupt-driven wake-up, SPI®-compatible serial interface, 50 Hz sensor bandwidth, auxiliary 12-bit ADC input and 12-bit DAC output, auxiliary digital input/output, single-supply operation: 4.75 V to 5.25 V, 2000 g powered shock survivability.
The ADIS16250 and ADIS16255 are compact, low‑power angular‑rate measurement systems that integrate a MEMS gyroscope with on‑chip signal processing. They provide factory‑calibrated digital outputs via a standard SPI serial interface and include features such as auto‑zero bias calibration, configurable sample rates, and low‑power modes.
The devices operate from a single 4.75 V – 5.25 V supply, survive 2000 g shocks, and are rated for an ambient temperature range of –40 °C to +85 °C. Detailed specifications, pin descriptions, timing diagrams, and recommended PCB layout are provided for hardware designers.
