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
