PRODUCT DESCRIPTION
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.

FEATURES
  Full-scale frequency (up to 2 MHz) set by external system clock
  Extremely low linearity error (0.005% max at 1 MHz FS, 0.02% max at 2 MHz FS)
  No critical external components required
  Accurate 5 V reference voltage
  Low drift (25 ppm/°C max)
  Dual- or single-supply operation
  Voltage or current input
  MIL-STD-883 compliant versions available
