AD650SD, VFC/FVC Non-Sync 1MHz 14-Pin SBCDIP Tube

AD650 is a voltage-to-frequency or frequency-to-voltage converter. It provides a combination of high frequency operation and low nonlinearity previously unavailable in monolithic form. The inherent monotonicity of the V/F transfer function makes the device useful as a high-resolution analogue-to-digital converter. A flexible input configuration allows a wide variety of input voltage and current formats to be used, and an open-collector output with separate digital ground allows simple interfacing to either standard logic families or opto-couplers. The input signal range and full-scale output frequency are user programmable with two external capacitors and one resistor. Input offset voltage can be trimmed to zero with an external potentiometer.
