AD7609BSTZ

AD7609 is an 18-bit, 8-channel, true differential, simultaneous sampling analogue-to-digital data acquisition system (DAS). The part contains analogue input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, an 18-bit charge redistribution successive approximation analogue-to-digital converter (ADC), a flexible digital filter, a 2.5V reference and reference buffer and high speed serial and parallel interfaces. Typical applications include power-line monitoring and protection systems, multiphase motor control, instrumentation and control systems, multiaxis positioning systems and data acquisition systems(DAS).
