Description

IC - SYNC V/F CONVERTER

The AD652 synchronous voltage-to-frequency converter (SVFC) is a powerful building block for precision analog-to- digital conversion, offering typical nonlinearity of 0.002% (0.005% maximum) at a 100 kHz output frequency. The inher- ent 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 uses a variation of the charge-balancing technique to perform the conversion function. The AD652 uses an external clock to define the full-scale output frequency, rather than relying on the stability of an external capacitor. The result is a more stable, more linear transfer function, with significant application benefits in both single- and multichannel systems. Gain drift is minimized using a precision low drift reference and low TC, on-chip, thin-film scaling resistors. Furthermore, initial gain error is reduced to less than 0.5% by the use of laser- wafer-trimming. The analog and digital sections of the AD652 have been designed to allow operation from a single-ended power source, simplifying its use with isolated power supplies. 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 commercial temperature range. The 16-lead CERDIP-packaged AQ and BQ grades are specified for operation over the −40°C to +85°C industrial temperature range. The AD652SQ is available for operation over the full −55°C to +125°C extended temperature range.
