PRODUCT DESCRIPTION
The AD652 synchronous voltage-to-frequency converter (SVFC) is a powerful building block for precision analog-todigital conversion, offering typical nonlinearity of 0.002% (0.005% maximum) at a 100 k Hz output frequency. The inherent monotonicity of the transfer function and wide range of clock frequencies allow the conversion time and resolution to be optimized for specific applications.
The AD652 is available in five performance grades. The 20-lead PLCC-packaged JP and KP grades are specified for operation over the 0°C to +70°C mercial temperature range. The 16-lead CERDIP-packaged AQ and BQ grades are specified for operation...
