The ADXRS450 is an angular rate sensor (gyroscope) intended for industrial, medical, instrumentation, stabilization, and other high performance applications. An advanced, differential, quad sensor design rejects the influence of linear acceleration, enabling the ADXRS450 to operate in exceedingly harsh environments where shock and vibration are present.The ADXRS450 uses an internal, continuous self-test architecture. The integrity of the electromechanical system is checked by applying a high frequency electrostatic force to the sense structure to generate a rate signal that can be differentiated from the baseband rate data and internally analyzed.The ADXRS450 is capable of sensing angular rate of up to ?300?/sec. Angular rate data is presented as a 16-bit word, as part of a 32-bit SPI message.The ADXRS450 is available in a cavity plastic 16-lead SOIC (SOIC_CAV) and an SMT-compatible vertical mount package (LCC_V), and is capable of operating across both a wide voltage range (3.3 V to 5 V) and temperature range (?40?C to +105?C).APPLICATIONSRotation sensing medical applicationsRotation sensing industrial and instrumentationHigh performance platform stabilization

The ADPD2214 is an optical sensor optimized for biomedical applications. Very low power consumption and near theoretical signal-to-noise ratio (SNR) are achieved by packaging an ultralow capacitance deep junction silicon photodiode operated in zero bias photoconductive mode with a low noise current amplifier. The ADPD2214 offers a typical 75 kHz bandwidth performance, which is well suited for use with pulsed excitation. The ADPD2214 uses very little power during operation and incorporates a power-down pin, enabling power cycling to optimize battery life in portable applications. The ADPD2214 provides shot noise limited performance, making it an excellent choice for measuring signals with the highest possible fidelity in low light conditions.
