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 inherent 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/℃ max)
● Dual- or single-supply operation
● Voltage or current input
● MIL-STD-883 compliant versions available
