Task 1: Below is picture from the Analog Devices MEMS accelerometer (model ADXL1004) datasheet. Your task is to search the datasheet for information about the sensor's characteristics and answer questions below. SPECIFICATIONS TA = 25°C, VDD = 5.0 V, acceleration = 0 g, unless otherwise noted. All minimum and maximum specifications are guaranteed. Typical specifications may not be guaranteed. Table 1.
