Versatile Monolithic V/f or I/f Converter

AD537 is Easy to Use, Works from Single Supply; Outputs to Beyond 100kHz; T/f Conversion Inherent

The AD537 is a self-contained monolithic voltage-to-frequency converter fabricated on a single 74 x 118 mil (1.9 x 3mm) silicon chip and mounted in a hermetically-sealed 14-pin ceramic dual in-line package (DIP). It contains an input amplifier, a precision oscillator system, a reference generator, and a high-current output stage. Read full article
