Datasheet Analog Devices AD652KP

Monolithic Synchronous
Voltage-to-Frequency Converter
AD652
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. 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 PRODUCT HIGHLIGHTS
1. The use of an external clock to set the full-scale frequency
allows the AD652 to achieve linearity and stability far
superior to other monolithic VFCs. By using the same clock …
