The AD7609 is an 18-bit, 8-channel, simultaneous sampling analog-to-digital data acquisition system (DAS). The part contains an 18-bit charge redistribution successive approximation analog-to-digital converter (ADC).The AD7609 operates from a single

Also called Q-formatFractional representation suitable for DSP algorithms.Fractional number range is between 1 and -1 Multiplying a fraction by a fraction always results in a fraction and will not produce an overflow (e.g., 0.99 x 0.9999 less than 1)
